Abstract
The permanent magnet synchronous motor is a kind of multivariable, strong coupling and nonlinear system, which applied to traditional PID control is difficult to achieve a good control effect. Based on the mathematical model of permanent magnet synchronous motor, a kind of speed control scheme which based on fuzzy adaptive PID control was proposed. Apply fuzzy adaptive PID to the control of permanent magnet synchronous motor, and use fuzzy control principle to set the PID parameters online, and then realize the optimal control. The simulation results show that, compared with the traditional PID control, the fuzzy adaptive PID control has the advantages of fast speed response, small overshoot and so on, the system has a strong robustness to the disturbance and the change of parameters, which achieve a better control effect.
