Control of Permanent Magnet Synchronous Motor Based on Active Disturbance Rejection Control

Abstract

Abstract For the control of permanent magnet synchronous motors, the proportional integral controller has the characteristics of simple structure and strong versatility, and has been widely used. However, in some occasions with the higher requirements for anti-interference, the proportional integral controller cannot fully meet the control requirements. Therefore, it is proposed to apply active disturbance rejection controller to control permanent magnet synchronous motors to achieve the purpose of improving the control performance of the system. The models of the proportional-integral controller and active disturbance rejection controller were built using MATLAB, and compared with each other under the premise of ensuring that both parameters were optimal. The situation proves that the permanent magnet synchronous motor with applying active disturbance rejection controller has better anti-interference performance in the interference environment.
