The control theory of permanent magnet synchronous motor based on anti-windup control

This article reviews and compares several aspects of permanent magnet synchronous motor speed control method of the anti-windup. In generally, motor control aspects of the state equation is modeled as linear systems in real-time control systems, at the same time the system will generate much higher than normal current and voltage values. Therefore, PI control is likely to have links to over-amplification of the control value, This phenomenon is called over-saturation of the motor, The existence of this phenomenon will cause the system to non-normal operation, causing system instability. So we will see in the article, several anti-saturation control algorithms, they will be in permanent magnet synchronous motor sensorless vector control algorithm and control algorithm for anti-saturation control and the speed controller in its use, to reduce saturated part of the motor speed, and the comparison of each other.
