Position Control of Servo Motor Using Sliding Mode Fuzzy Controller
نویسندگان
چکیده
This paper deals with the development of different control techniques such as Fuzzy, Sliding mode, and Sliding Mode fuzzy controllers for the servo drive system. Servomotors are widely used in industry due to their relatively low cost and high reliability. To get high performances we have to control the input variable in uncertainties and disturbance. Two cases are discussed for each control scheme. Normal case, parameter variation case, and disturbance case are considered. When fuzzy Controller is implemented in the system. Fuzzy controller gives better performance compared to other controllers but results are ineffective for disturbance case. Sliding mode fuzzy control is then implemented. It is observed that system performance increases when compared to fuzzy control for parameter variation case and for disturbance case which shows the robustness of SMFC. So sliding mode fuzzy control is superior when compared to other controller in terms of control performance. Various control schemes are then compared with each other. Simulations are carried out on MATLAB. Index Terms SMC, Fuzzy Logic, SMFC, Servo Drive

The thin-disc piezoceramic-driving ultrasonic actuator dedicated to a stepping ultrasonic motor is proposed. The mechanical hysteresis and dead-zone phenomena are automatically compensated by a closed loop servo control, i.e. Fuzzy Sliding-Mode Control (FSMC), for position tracking. The controller design of FSMC has syncretized the fuzzy reasoning and sliding mode control with robust stability ...
