Improved Speed Response of ECM Drive Using Antiwindup Concept

Recently, the ECM (electronic communicated motor) is gaining popularity in automation area, and household applications due to its cheapness, accessible regulation techniques, the lesser part maintaining and large range torque. But due to nonlinearity behavior of ECM motor just like saturation, disturbance etc. speed response is disturbed from the desired output. In my paper, starting torque or starting current has to be reduced by using a saturation technique, but speed response is not according to desired outputs. So to sort out this problem we will use Antiwindup PID instead of conventional PID. In closed loop system speed deterioration happens due to saturation of the integral part of PID which is known as windup problem. Same windup problem cause increase in overshoot and settling time of speed and torque characteristics. The ECM drive system along with Antiwindup PID and current controller has been developed in the MATLAB, Simulink Dynamic behavior of the system has been systematically studied and to prove system effectiveness and validity. Comparative study has been done to understand the differences in response.
