Adaptive-fuzzy PI control strategy for flux-switching permanent magnet motors

摘要

The parameters of flux switching permanent magnet motor are very nonlinear, so it is of great significance for its extensive use with good adjustable speed performance in a wide speed range. In this paper, according to the characteristics of both fuzzy controller and PI controller, a fuzzy self-tuning PI controller is proposed, which is suitable for the digital speed control system of FSPM motor. Under the control strategy, which is simple and easy to realize, the drive system has achieved remarkable results in depressing both the overshoot and disturbance. Both the simulation and experimental results show that the proposed control strategy has good steady and dynamic performance.
