Tangqing Hu, Xuxiu Zhang · 2019 IEEE International Conference on Power, Intelligent Computing and Systems (ICPICS) · 2019
PMSM has the characteristics of nonlinearity, strong coupling, and time-varying parameters. The parameters of PI controller cannot make self-tuning with the change of system state. This paper proposes a new fuzzy control rule. The proportion factor can be adjusted online. The simulation results show that fuzzy PI controller speed regulation system with improved fuzzy rules has faster response speed, small overshoot and strong anti-interference ability. The control system with improved rules has better control performance.
