Study on a Novel Control System of PMSM

Ke Zhao, Hanying Gao, Abdolreza Esmaeli, Li Zhong Sun

Abstract

A novel PMSM servo-system is introduced in this paper, and a double closed-loop control system with the current and speed loop is applied. The speed controller adopts compound control strategy with parameter self-adjust fuzzy control and PI control. At the same time, the current loop adopts PI control. Considering the dynamic performance of PMSM, the vector control and SVPWM is employed. The experiment results show that this control system possesses good dynamic and static performance, such as quick response and strong robustness.
