PI anti-windup speed control of permanent magnet synchronous motor based on feedforward compensation

Abstract

This paper designs simulation model of PI anti-windup speed controller based on a simple set-point weighting for the interior permanent-magnet synchronous motor (IPMSM). Firstly, a mathematical model of IPMSM drive system utilized in the simulation is introduced. Also, the maximum torque per ampere (MTPA) control suitable for IPMSM was employed. This controller is simple for implementation in practice and it has advantages over a conventional PI controller. The proposed anti-windup PI controller demonstrates better dynamic step changes response in speed in terms of overshoots, improved settling time, and improved robustness to parameter variations in comparison with conventional PI. The performance of proposed PI anti-windup controller with set-point weighting was compared with the conventional PI.
