A Proposed Simulation Approach for Teaching the Design of a DC Motor using MATLAB

This paper deals with the design of speed and torque control of DC motor drive. The PI control scheme is proposed for the system, and it is usually used in DC motor drives. The proposed control schemes guarantee the asymptotic stability of the closed-loop system. The converter that is used in the system is a 4-quadratic switch-mode DC-DC converter. The design is based on a small signal model and verified using a large signal model. To illustrate the developed control schemes, the performance of the closed loop system is simulated using MATLAB. The simulation, analysis, and discussion are introduced to present the efficiency of the scheme.

속도 프로파일 기반의 가감속제어를 통한 DC 모터의 토크제어

본 논문에서는 자동물류운반시스템(AGV)에 사용되는 가감속 제어를 위한 속도 프로파일 기반의 가감속 위치제어를 DC 모터 실험을 통한 토크변화에 대해서 고찰한다. 속도 프로파일을 이용한 모터의 가감속 제어는 모터에 걸리는 부하를 줄임으로써 시스템의 무리한 구동을 방지하고 수명을 연장 시키는 장점을 가지고 있다. 체계적인 설계 구조를 갖는 상태 피드백 제어기를 이용하여 속도 프로파일을 이용한 가감속 제어 기반의 DC 모터의 위치제어와 단순 위치제어를 모의실험을 통하여 비교함으로써 토크 크기를 비교 관찰한다. 또한 CEM-IP-01의 카트 위치 제어 실험을 통하여 이를 검증한다. This paper presents torque control of DC motor using the velocity profile based acceleration/deceleration controller for automatic guided vehicles (AGVs). This technique has some advantage; to reduce the damage of motors and to extend the life time of motors. First, we generate velocity profiles for three cases and design the state feedback controller using the generated velocity profile as a reference. The state feedback controller has servo system for solving regulation problem. For the verification, we apply the proposed method to control a cart position and shows some simulation result.

Design of DC motor's torque control using DSP

DC motors are often used in many industrial applications requiring high torque, and different motor's torques should be necessary for different loads. The torque will not be sufficient to drive the heavy load for constant current control of a DC motor. Therefore, for wider range of current variations for the applications of DC motor, the load current is taken as feedback signal for the fuzzy controller, the suitable duty cycle will be obtained by fuzzy logic operations. The desired duty cycle is used as the input signal for the boost converter to change the load current. To realize the different driving torques for different loads, desired current of the DC motor is offered. Finally, the digital signal processor (DSP) is used to achieve the torque control of the DC motor for different loads.

Design and Implementation of Electronic System and Computer Control of an Indexing Table and Quality Control Unit

Capability and meanwhile simplicity have stupendously expanded the area of application of linear controllers in the industrial activities, particularly the control of robotic arms, and other devices. The ultimate goal to accomplish this project is to show this capability in the frame of movement control of the arm of a quality control unit (side device), which forms a part of an automatic cell together with an indexing table. The fact that the existence of the gearbox, dramatically decreases the effects of non-linear dynamic of the arm to linear dynamic of the DC motor, justifies the idea of designation and implementation a linear controller like Lead-Lag to control the said arm. Of course, we need to apply some other equipment like DC motor torque control system, sensors, and related interface circuits. In this article, it will be observed that how the above goal will be accomplished by linear identification of the system with the method of step response identification and then digital implementation of the said controller in computer and application of the arm motor torque control.
