An Adaptive-fuzzy PI Control Strategy for Flux-switching Permanent Magnet Motors

磁通切换永磁电机参数具有很强的非线性,因此若能够在宽的速度范围内具有较好的调速性能,对该型电机的广泛应用具有重要意义。该文根据模糊控制器和PI控制各自特点,提出适应数字化磁通切换永磁电机调速系统的模糊自适应PI控制器,该控制策略算法简单且易于数字化实现,调速系统在抑制超调和抵抗扰动方面取得了明显的效果,具有良好的稳态和动态性能,仿真和实验结果验证了所提控制策略的有效性。

The parameters of flux switching permanent magnet（FSPM） motors are very nonlinear, so it is of great significance for its extensive use with good adjustable speed performances in a wide speed range. In this paper, according to the characteristics of both fuzzy controllers and PI controllers, a fuzzy self-tuning PI controller is proposed, which is suitable for the digital speed control system of FSPM motors. Under the control strategy, which is simple and easy to be realized, 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 performances
