Active compliance control of grinding process for stripping enameled copper wire

The hairpin motor is among the motors used in eco-friendly automobiles. Unlike the random-winding method, this method features a square cross-sectional enamel coil formed into several hundred hairpins inserted into the stator. This offers an increased space factor, which leads to enhanced motor power. With the growing use of hairpin motors, there is an increasing demand for automated equipment in their production. With an aim to improve the manufacturing quality of hairpin motors, many countries are conducting research and development. The process of enamel removal is one of the key steps in hairpin-forming equipment and can significantly affect the performance of the motor. A precise machining process technology is required to improve the enamel removal process, achieve higher enamel removal rates, and reduce wire loss rates. Grinding is a technique used for enamel removal. In this study, an adaptive control algorithm was applied to the grinding process to enhance the enamel removal machining performance. During the machining process, the vertical position of the spindle was controlled to maintain a consistent machining depth for tracking the target grinding force. An experimental setup, which included a system for measuring the spindle torque to calculate the grinding force in real time, was created. To validate the performance of the adaptive control technology, experiments were conducted using this setup. Furthermore, experiments were conducted to observe the changes in the grinding force ratio based on the conditions of the grinding wheel. The correlation between the grinding force ratio and tool condition was analyzed, and based on this, the feasibility of assessing tool condition and determining the timing for tool replacement through real-time monitoring of the grinding force ratio was confirmed.

Lessons from the pandemic era: do we need new strategies to improve conservative treatment adherence in adolescent idiopathic scoliosis? A retrospective analysis.

This study aims to examine whether the COVID-19 pandemic affected the adherence to conservative AIS treatment. Adolescent Idiopathic Scoliosis (AIS) is characterized by a lateral curvature of the spine of at least 10 degrees. Compliance rates in conservative treatments are influenced by various factors. From a database of AIS patients, we selected 30 AIS patients who were assessed before, during, and after the COVID-19 pandemic. Data regarding Cobb's angle, brace prescription, prescribed brace wear time, brace wear compliance, and time dedicated to sports activities were collected over a six-year period from January 2018 to December 2023, divided into three 2-year time periods (before, during, and after COVID-19). There was an increased percentage of AIS patients prescribed with a brace during the pandemic. However, no significant differences in Cobb's angle were observed. Additionally, the prescribed wear time showed a significant decrease from the pre-COVID period to the post-COVID period (p-value = 0.03). Wear compliance exhibited a decreasing trend from pre- to during- and post-COVID-19 periods without reaching statistically significant differences, and the time dedicated to sports statistically significantly decreased. These differences were statistically significant when comparing the pre- vs. post- and pre- vs. during-COVID-19 periods (p-values 0.01, 0.04, respectively). Our study highlights changes in AIS conservative treatment during and after the COVID-19 pandemic. The increase in the number of patients prescribed with a brace during the pandemic, although not supported by an increase in Cobb's angle, may be attributed to the concerns about regular monitoring during the reduction of rehabilitation services. The observed decreases in brace compliance and involvement in sport activities, which persisted even in the post-pandemic period, emphasizes the lasting impact of the pandemic on AIS management, necessitating innovative approaches to address these ongoing concerns.

Physical Activity and Perceived Support among Adolescents According to Sex and Municipality.

A cross-sectional study was conducted with three aims: (1) to determine the degree of compliance with physical activity recommendations among adolescents according to sex and place of residence, (2) to determine the perceived support of family and friends for physical activity among adolescents according to sex and place of residence, and (3) to analyse the influence of family and friends support on compliance with physical activity recommendations among adolescents according to sex and place of residence. A total of 694 adolescents from an inland area of Spain (14.06 ± 1.27 years) participated. Four one-day physical activity questionnaires were administered to assess physical activity and the Parental Support Scale and Peer Support to measure perceived support from family and friends regarding physical activity. Chi-square, Crammer's V and Student's tests were calculated to identify differences between variables according to sex and municipality of residence. Moreover, the initial binary logistic regression model was constructed to predict the physical activity compliance. Differences in adherence to physical activity recommendations were found according to the sex of the students (rural area: x2 = 4.192, p < 0.05; V = 0.106, p < 0.05; urban area: x2 = 8.999, p < 0.05; V = 0.167, p < 0.01). There were also sex differences in rural areas on items related to families providing transport (t = 3.878, p ≤ 0.001; d = 0.40) and doing physical activity together (t = 4.974, p ≤ 0.001; d = 0.50). It is concluded that most adolescents do not comply with physical activity recommendations. In addition, 30.4% of urban girls' compliance was predicted by the perception that their family members saw them doing physical activity and doing it with friends.

Focus on the effect of nursing care combined with cognitive intervention and functional training on negative emotion, compliance and quality of life in elderly patients with sudden deafness: A retrospective study.

To explore the effects of focused solution nursing combined with cognitive intervention combined with functional training on negative emotions, compliance and quality of life in elderly patients with sudden deafness. A total of 160 patients with sudden deafness in the elderly who were treated in our hospital from January 2019 to May 2021 were selected as the objects of this retrospective study. Based on different treatment approaches, subjects were divided into a control group and an observation group. Due to reasons such as the COVID-19 pandemic and transfers, 10 cases were lost to follow-up. In total, 75 cases were ultimately lost from both the control and observation groups. The control group implements cognitive intervention and functional training, and the observation group adopts focused solution nursing care on the basis of the control group. Observe and compare the effects of negative emotions, psychological distress, air conduction threshold level, compliance and quality of life of the 2 groups of patients. The air conduction hearing threshold level of the 2 groups of patients after nursing was lower than that before nursing and the observation group was lower than the control group. The positive coping scores of the 2 groups were significantly increased, and the negative coping scores were both significantly reduced and the observation group was in the 2 indicators. The degree of change was greater than that of the control group (P < .05). After nursing, the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) of the observation group were lower than those of the control group (P < .05). The mental vitality score, social interaction score, emotional restriction score, and mental status of the observation group were significantly higher than those of the control group. The observation group's psychological compliance, activity compliance, dietary compliance, and treatment protocol compliance were significantly higher than those of the control group (P < .05). Adopting the focused solution model of nursing care can provide a better nursing recovery for elderly patients with sudden deafness, significantly improve the patient quality of life and anxiety and depression, improve patient compliance with treatment, and provide a certain reference for the nursing of elderly patients with sudden deafness.

Research on Mechanical Leg Structure Design and Control System of Lower Limb Exoskeleton Rehabilitation Robot Based on Magnetorheological Variable Stiffness and Damping Actuator

During the walking process of lower limb exoskeleton rehabilitation robots, inevitable collision impacts will occur when the swinging leg lands on the ground. The impact reaction force from the ground will induce vibrations in the entire robot’s body from bottom to top. To address this phenomenon, considering the limitations of traditional active compliance and passive compliance methods, a variable stiffness and damping actuator (VSDA) leg structure using a magnetorheological damper (MRD) is proposed. Firstly, experimental methods are used to obtain the ground reaction force (GRF) exerted on a normal person during walking. Then, a mathematical model of the VSDA leg structure is constructed, and its working principle is analyzed. Based on human mass and dimensions, a 3D model is designed and selected. Finally, a simulation model is built in the MATLAB/Simulink environment using the fuzzy switch damping control strategy to simulate the acceleration and displacement of the human body under sinusoidal and random excitations. The results indicate that under sinusoidal excitation, employing fuzzy switch damping control optimizes human displacement by 72.47% compared to the high stiffness and high damping system, and by 16.95% compared to the switch damping system. Human acceleration is optimized by 52.09% compared to the high stiffness and high damping system, and by 25.2% compared to the switch damping system. Under random excitation, adopting fuzzy switch damping control optimizes human displacement by 59.09% compared to the high stiffness and high damping system, and by 21.74% compared to the switch damping system. Human acceleration is optimized by 78.74% compared to the high stiffness and high damping system, and by 31.66% compared to the switch damping system. This validates the VSDA design structure and control method, demonstrating certain advantages in improving the compliance and stability of lower limb exoskeleton rehabilitation robots.

Compliance as a Tool for Ensuring the Economic Security of an Organization: Problems and Prospects of Application

Compliance is applicable in any organization and acts as one of the modern types of control, during which the compliance of the organization's activities with the norms of national legislation is monitored. This tool provides real protection against corruption, conflict of interest, and contains in its arsenal a whole range of elements that can be implemented in the organization's economic security system. Compliance allows you to identify the risks of the organization's functioning at the early stages of manifestation and prevent the application of sanctions by regulatory authorities, and subsequently prevent economic damage. The authors present approaches to the definition of the term, types of compliance, and a comparative analysis of compliance with other types of control, confirming its uniqueness. According to the authors, one of the disadvantages in the development of compliance is its reduction to a set of formal management standards and procedures. The authors concluded that this is not just an element of corporate governance, but also an effective way to prevent corruption crimes. The prospects of using this tool in modern conditions of global instability and the development of digital management methods are considered.

Jamming problems and the effects of compliance in dual peg-hole disassembly

Disassembly is a crucial step in remanufacturing and is currently mainly performed by humans. Automating disassembly can reduce labour costs and make remanufacturing more economically attractive. This paper focuses on identifying and characterizing a common disassembly task, dual peg-hole disassembly, with the aim of building a robotic disassembly system for this task. We enumerate the possible contact states and their geometric conditions during the extraction of two studs in a dual peg-hole. This paper focuses on jamming in the extraction and conducts geometrical and quasi-static analyses to determine the boundary conditions of jamming. Based on the analyses, this paper also investigates the role of active compliance as a solution to avoid jamming. We also simulate critical variables and examine key parameters such as the degree of compliance, the location of the compliance centre and initial position errors. Finally, we conduct experimental studies on dual peg-hole extraction with different compliance centres obtained using active compliance.

Proxy-Based Sliding Mode Force Control for Compliant Grinding via Diagonal Recurrent Neural Network and Prandtl-Ishlinskii Hysteresis Compensation Model

Traditional industrial robots often face challenges in achieving a perfectly polished surface on a workpiece because of their high mechanical rigidity. The active compliance force control device installed at the robotic arm’s end enables high-precision contact force control between the grinding tool and the workpiece. However, the complex hysteresis nonlinearity between cylinder air pressure and output force, as well as various random disturbances during the grinding process, can affect the accuracy of the contact force and potentially impact the grinding effect of the workpiece, even causing irreversible damage to the surface of the workpiece. Given the complex random variation of cylinder output force in the actual grinding process, a rate-dependent hysteresis model based on diagonal recurrent neural network and Pradtl–Ishlinskii models named dRNN-PI is designed to compensate for the complex nonlinear hysteresis of the cylinder and calculate the desired air pressure to maintain a steady contact force on the workpiece. The proxy-based sliding mode control (PSMC) is utilized to quickly track the desired air pressure without overshooting. This paper also proves the controller’s stability using the Lyapunov-based methods. Finally, the accuracy of the proposed hysteresis compensation model and the effectiveness and robustness of the PSMC are verified by experiment results.

Inverse-Reinforcement-Learning-Based Robotic Ultrasound Active Compliance Control in Uncertain Environments

Robotic ultrasound systems (RUS) have gained increasing attention because they can automate repetitive procedures and relieve operators' workloads. However, the complexity and uncertainty of the human surface pose a challenge for stable scanning control. This paper proposes a general active compliance control strategy based on inverse reinforcement learning (IRL) to perform adaptable scanning for uncertain and unstructured environments. We analyze the manual scanning process pattern and propose a velocity-and-force-related control strategy to achieve variable force control and handle unpredictable deformation. Then, a hybrid policy optimization framework is proposed to improve transferability. In this framework, a reinforcement learning (RL) policy with a predefined reward is built to establish the relationship between contact force and posture. Furthermore, the policy is re-optimized using IRL and generated demonstrations for IRL training. The policy is trained on simple standard phantoms and further evaluated for stability and transferability in unseen and complex environments. Quantitative results show that the difference between the proposed method and the 3-D reconstructed model in terms of posture is (2.3±1.3°, 1.9±1.2°) in continuous scans. Overall, our method provides a solution for improving the usability of robotic ultrasound systems in real-world environments.

Active Compliance Smart Control Strategy of Hybrid Mechanism for Bonnet Polishing.

Compliance control strategies have been utilised for the ultraprecision polishing process for many years. Most researchers execute active compliance control strategies by employing impedance control law on a robot development platform. However, these methods are limited by the load capacity, positioning accuracy, and repeatability of polishing mechanisms. Moreover, a sophisticated actuator mounted at the end of the end-effector of robots is difficult to maintain in the polishing scenario. In contrast, a hybrid mechanism for polishing that possesses the advantages of serial and parallel mechanisms can mitigate the above problems, especially when an active compliance control strategy is employed. In this research, a high-frequency-impedance robust force control strategy is proposed. It outputs a position adjustment value directly according to a contact pressure adjustment value. An open architecture control system with customised software is developed to respond to external interrupts during the polishing procedure, implementing the active compliance control strategy on a hybrid mechanism. Through this method, the hybrid mechanism can adapt to the external environment with a given contact pressure automatically instead of relying on estimating the environment stiffness. Experimental results show that the proposed strategy adapts the unknown freeform surface without overshooting and improves the surface quality. The average surface roughness value decreases from 0.057 um to 0.027 um.

Design, self-calibration and compliance control of modular cable-driven snake-like manipulators

The high flexibility of cable-driven snake-like manipulators (CDSM) makes them well-suited for tasks in narrow and unstructured spaces. However, ensuring both stiffness and load capacity while maintaining good compliance for safe human-robot interaction is challenging. We design a modular cable-driven snake-like manipulator (MCDSM) and improve its active compliance through impedance control. Firstly, the detachable arm segments of the MCDSM can adapt to multiple tasks. The modular drive units and plug-in drive boxes facilitate quick installation and maintenance. Furthermore, the modified kinematic model considers the torsion angle information of the detachable arm segments. Based on this model, a self-calibration method using redundant cable length is proposed for cable space to joint space. Moreover, a dynamic model for the MCDSM is established. An optimization method for cable tension in joint space is proposed to eliminate the coupling phenomenon during tension control. Finally, a compliant control method for the MCDSM is presented by combining the inner loop for the cable tension control. The feasibility of the proposed methods is demonstrated through simulations and experiments with a prototype.

Power trading Raft consensus mechanism considering green certificate and carbon emission weights

The consensus mechanism is a critical technology in the power trading blockchain distributed power trading platforms, which are gradually being applied and promoted to achieve the “dual carbon” goal. Green-certificate trading and carbon emission trading systems help mobilize power generation enterprises to increase the generation of and investment in renewable energy, thereby becoming important factors in distributed power trading. Therefore, they should also be considered as factors in the consensus mechanism. This article first evaluates the green-certificate weight based on whether nodes possess green certificates, evaluates the carbon emission weight based on the carbon emission settlement of nodes in the previous cycle, and constructs a mechanism to evaluate a node’s weight. An improved Raft consensus algorithm based on node weight is then proposed. Nodes with greater weights are more likely to become leading nodes, promoting active compliance and green consumption by nodes and reducing carbon emissions. A simulation shows that the improved Raft consensus mechanism enhances the reliability of leading nodes, improves the efficiency of the distributed power transaction, increases the generation of renewable energy, and encourages the consumption of new energy.

Current trauma team activation processes at Canadian trauma centres: A national survey

BackgroundTrauma team activation (TTA) allows the provision of specialized and timely care to improve outcomes for severely injured patients. Limited information is available on the current state of TTA in Canadian trauma centres (TC). Study objectives were to describe TTA processes, data and reports, along with the challenges and successes from a national perspective. MethodsA mixed-methods, cross-sectional survey was undertaken with Canadian trauma leadership, utilizing a total population sampling strategy. The questionnaire, containing 108-items, was administered online between February-April 2022, utilizing a modified Dillman technique. Descriptive statistics and thematic analyses were performed. ResultsTrauma leaders from 9 out of 10 provinces responded for a response rate of 68% (32/47). Two-thirds (67%) of respondents worked in adult TC; 63% in a level I center. A higher proportion of pediatric TC had a two-tiered TT response (60% pediatric; 35% adult). The most common criteria were neurologic compromise (100% one-level TTA) and hypotension (pediatric: 100% one-level, 100% tier 1; adult: 92% one-level, 86% tier 1). All one-level TTA included penetrating trauma criteria. One-third of respondents reported using TTA subgroup criteria for pediatric, pregnant, and/or geriatric patients. There was variability with disciplines responding to TTA, with largest, most comprehensive teams for tier 1. Two-thirds of TC review activation compliance (under/overtriage), while 55% focus on non-compliance and reasons for missed TTA. The most frequent challenges related to TTA practices were reliable data collection (60%) while successes included were the establishment of TTA guidelines to improve team compliance (33%) and RN initiated TTA. ConclusionsSome TTA practices were similar among Canadian TC, while others showed variability. Findings provide opportunities for improvement, including a two-tier system, geriatric-specific criteria, and RN initiated TTA, and could help establish national standards and best practices. Compliance with standards has the potential to improve Canadian TTA practices and patient outcomes.

Design control and actuator selection of a lower body assistive exoskeleton with 3-D passive compliant supports

Physical human–robotic interaction is a crucial area of concern for robotic exoskeletons. Lower weight requirement for the worn exoskeletons limits the number and size of joint actuators, resulting in a low active degree of freedom for the exoskeletons with joint actuators having limited power and bandwidth. This limitation invariably results in reduced physical human–robotic interaction performance for the exoskeleton. Recently several techniques have been proposed for the low active degree of freedom exoskeletons with improved physical human–robotic interaction performance using better load torque compensators and improved active compliance. However, effective practical implementation of these techniques requires special hardware and software design considerations. A detailed design of a new lower body exoskeleton is proposed in this paper that can apply these recently developed techniques to practically improve the physical human–robotic interaction performance of the worn exoskeletons. The design presented includes the exoskeleton's structural design, new joint assemblies and the design of novel 3-D passive, compliant supports. A methodology of selecting and verifying the joint actuators and estimating the desired assistive forces at the contact supports based on human user joint torque requirements and the degree of assistance is also thoroughly presented. A new CAN-based master–slave control architecture that supports the implementation of recent techniques for improved physical human–robotic interaction is also fully presented. A new control strategy capable of imparting simultaneous impedance-based force tracking control of the exoskeleton in task space using DOB-based-DLTC at joint space is also thoroughly presented. Simulation verification of the proposed strategy based on the actual gait data of elderly is presented lastly.
