DsPIC Implementation and Performances Evaluation of Adaptive Filters for System Identification

This paper aims to implement and evaluate performances of adaptive filters applied to linear systems identification on a dsPIC platform. To do so, we considered two different applications: the identification of DC motor transfer function and the acoustic echo cancellation. For the DC motor case, real-time identification is not necessarily required. However, for the acoustic echo cancellation case, real-time identification is crucial, making execution time a key parameter in this scenario. We have implemented three adaptive algorithms: LMS, NLMS, and RLS. The first two are known for their computational simplicity, while RLS is recognized for its convergence speed. Performances evaluation is primarily based on accuracy and computation speed. A comparison is carried out in both cases to determine which algorithm is more suitable for each application. The results obtained showed that RLS is better suited for the DC motor case, while NLMS is more suitable for acoustic echo cancellation, particularly when the impulse response of the echo path is long.

DC Motor PID Control System for Tamarind Turmeric Herb Packaging on Rotary Cup Sealer Machine

The end of this research is to find PID tuning value on the packaging automation process using the PID method. By finding the most suitable PID tuning value, a fast packaging process is obtained. Herbal ingredients in herbs that are left in the open for a long time tend to be damaged more quickly. So after the production process ends, the herbs must be packaged quickly. With the packaging automation method, the product can be hygienic and does not spoil quickly. One of the most widely and easy-to-use for automation methods in the industry is the PID control method because it can accelerate the system response, stabilize the system to match the setpoint and minimize overshoot. This study will discuss how the design of the PID control system using DC motor transfer function modeling in Matlab and the Second Ziegler-Nichols PID tuning method, the effect of the load on the motor response, and the effect of PID on the production speed. The system was tested with PID tuning values are Kp = 12, Ki = 12,506, Kd = 0.0028785, speed motor 24 RPM and a load of 3,160 Kg produces a good output response are delay time = 0.502 s, rise time = 0.804 s, settling time = 4.023 s, peak time = 133.084 s, Overshoot = 0.125% and Steady State Error = 0%. The effect of PID control on production speed is 83% faster than manual production and 29% faster than systems without PID.

Construction of Mathematical Model of DC Servo Motor Mechanism with PID controller for Electric Wheel Chair Arrangement

Low-level and medium-level leg injury patients can be operated wheelchair independently in the clinical region. The construction of an electric wheelchair is one of the solutions to operate electric wheelchair by the patients themselves. The motor is an essential part of an electrical wheelchair for driving from one place to another place. The response of the system is very important for the optimization of the system. The existing methods fail in gradual sensitivity during motion and lack of response time to the user. This article is consist of a design for optimizing the existing DC motor transfer function for the smart wheelchair. The perfect angular tuning of the derivative controller provides a better executing time for our proposed model. The smoother responses from the smart wheelchair are obtaining by the dynamic response of closed-loop control. The design of DC motors is to drive smart wheelchair as per the needs. Besides, the construction of a mathematical model for proposing a system involves the DC motor drive to the smart wheelchair arrangement. The proposed model gives independent mobility of smart wheelchair with less response time and better sensitivity. Here, the mathematical model provides the details of immediate response to the user and less execution time of the complex system process. Finally, the authors discussed future improvements to the current DC motor design in the proposed system.

DC motor simulation transfer function estimation: case study Proteus Ver. 7

Computing technology development today has a significant influence on the design process of a product or system even including the learning process in the field concerned. The electronics and control field is a field that greatly helped by these developments. Developments of electronic products or systems become faster and more efficient with the availability of CAD (Computer-Aided Design) software. Some Electronic CAD software provides DC motor model, as Proteus 7.0. Availability of this model is beneficial in control system designing and learning but the availability of a DC motor models are often constrained because are not accompanied with adequate information about internal parameters of the dc motor model or dc motor modeling done in programming so it is not possible to derive dc motor transfer function based on internal parameters. This study successfully showed transfer function derivation of dc motor in Proteus CAD simulation with a black-box approach for linear systems.

Dynamic Modeling and Coupling Characteristic Analysis of Two-Axis Rate Gyro Seeker

A dynamic model of a two-axis rate gyro-stabilized platform-based seeker with cross-coupling, mass imbalance, and disturbance torque is developed on the basis of the working principle of seeker two-loop steady tracking theory; coordinate transformations are used to analyze the effects of seeker servo control mode on missile guidance and control systems. Frequency domain is used to identify the servo motor transfer function. Furthermore, a block diagram of the two-gimbal-coupled system is developed, and the coupling characteristics of gimbal angle are analyzed with different missile body inputs. Simulation results show that the analysis conforms with the actual movement rule of seeker gimbal and optical axis, and cross-coupling exists between the two gimbals. The lag compensation network can increase the open loop gain and increase the capacity for disturbance rate rejection. Simulations validate the theory and technology support for developing the seeker servo control model in engineering.

Closed-Loop Estimation of Permanent Magnet Synchronous Motor Parameters by PI Controller Gain Tuning

In this paper, we present a closed-loop estimation method of permanent magnet synchronous motor parameters by PI controller gain tuning. The idea of the proposed method is to tune the controller to cancel the pole of the motor transfer function with a controller zero and estimate motor parameters from the tuned controller gains. The induced EMF is cancelled by a feedforward compensation term. A systematic tuning procedure is illustrated based on sound theoretical derivations. Compared with the conventional methods using system identification or phasor diagrams, the proposed method does not require complex data analysis or test configuration. Only simple calculation and tuning are sufficient to estimate motor parameters while meeting the desired closed-loop performance. Simulation and experiment are presented to validate the proposed method

Effect of source impedance on motor performance

TO DATE little attention has been focused on the resulting over-all system performance caused by the effect of driving source impedance on servomotor characteristics. The torque speed characteristics of a motor, as furnished by the manufacturer, may be correctly used for calculating the motor transfer function only when the identical test conditions relating to the driving source impedance to both phases are satisfied.
