Abstract

Abstract: In the direct instantaneous torque control system of switched reluctance motor, there is a nonlinear saturation in the speed outer loop controller. The integral control link of the controller will accumulate the error and increase the error gradually, resulting in the saturation effect of the controller and reducing the performance of the system. In this regard, an anti- windup adaptive PID controller is proposed on the basis of the traditional speed controller. This method integrates the input saturation error of controller and adjusts the integral term of controller by adaptive coefficient, so that it can quickly desaturation when the system has saturation overshoot. The simulation and test show that this method can suppress the saturation phenomenon, improve the motor response speed, reduce the ripple of speed, and achieve better system stability and robustness.
