用于永磁同步电动机驱动的模糊PI控制器设计

Design of Fuzzy PI Controller Used for Permanent Magnet Synchronous Motor

将模糊PI控制应用于控制永磁同步电动机,克服了基于空间矢量脉宽调制的永磁同步电动机参数的非线性、耦合性和运行过程中由于发热引起的电动机参数漂移的影响,达到较高的控制精度。实验表明采用模糊PI控制比传统的PI控制器具有更快的响应速度、更高的稳态精度和更强的鲁棒性。

This article introduces the application of fuzzy PI control on PMSM（Permanent Magnet Synchronous Motor）,which can avoid the non-linear,coupling and drifting of PMSM parameters based on space vector PWM.Compared with traditional PI controller,fuzzy PI controller is featured by fast reaction,higher state accuracy and robustness.
