Simulation Study and Speed Control of Permanent Magnet Synchronous Motor By Using Self-Tuning Fuzzy-PID Controller

: In recent years, permanent magnet synchronous motors (PMSM) are widely used in the mid-powerful servo motor drive because of their high power, torque and efficiency. Simualtion study was carried for speed control of PMSM using Matlab/Simulink software package. In this control method, Self-tuning fuzzy-PID controller and PID controller is first designed to apply to speed control unit of PMSM. Self-tuning Fuzzy-PID controller is developed using MATLAB/Simulink Fuzzy Logic Toolbox. Simulation studies are implemented for both of the controllers under same conditions. The results obtained from conventional PID controller and Self-tuning fuzzy-PID controller are analyzed and compared according todisturbance effects such as tracing different references speed and load torque. According to obtained simulation results, it is observed that Self-tuning fuzzy-PID controller provides better speed response than PID controller.
