Study on Induction Motor Servo System Based on Fuzzy Control Technology
The position-servo control of individual pitch control in wind power system request high-precision and faster response without overshoot, while existing load torque large-scale changing and the nonlinear characteristics. The conventional PID control method was difficult to meet the control requirements. We have developed a fuzzy servo control system for induction motor. In this paper, for overcoming the speed change caused by load torque changes, a fuzzy controller was set up as adjustor of the speed loop. Indirect vector control base on SVPWM was used in current loop. Controller Model of an Induction Motor based on Fuzzy SVPWM Vector Control was set up in MATLAB/simulink. Simulation results indicate that the system has rapid speed response and strong robustness.
