Abstract
This thesis focuses on the speed control of Permanent Magnet Synchronous Motor (PMSM) drive system with Fuzzy logic self-tuning PID controller using MATLAB/ Simulink 2015a. The performance of the proposed controller of PMSM was analyzed in terms of speed tracking capability, torque response quickness, high and low speed behavior, parameter sensitivity and speed reversal conditions. Comparison is also made between FPID with the conventional PI and PID controller mechanisms. The result shows that the FPID has more significant advantage in overshoot reduction by (11.7% and 21%) than PID and PI controllers and with very good steady state error of 0.035% without load test. While with load test the FPID controller have good performance with 0.043% steady state error percentage.
