This paper introduces tracking differentiator based on the classical PID control in order to arrange the transitional process according to the set point and control system parameters, solving the contradictions between speed and overshoot of the manipulated variable in the traditional PID control. At the same time, tracking differentiator provide an effective method of calculating differential with low noise amplification. Nonlinear PID controller adopts a nonlinear combination of error, error differential and error integral to calculate the controlled variable in a very effective way. Applying this kind of nonlinear PID controller to the permanent magnet linear synchronous motor control system , the experimental results show that PMLSM can follow the speed command quickly in no overshoot, and has strong robustness, good static and dynamic characteristics.
