摘　　要：为了提高调速系统的快速性、稳定性和鲁棒性,引入基于模糊控制理论的模糊PI来替代传统PI,然后从反电动势中提取转速和转子位置信号,实现了永磁同步电机转子位置检测,最后利用Matlab平台对提出方法进行验证。实验结果表明:模糊PI滑模观测器不仅鲁棒性强,而且在一定程度上提高调速系统的快速性、稳定性、可靠性,同时降低超调量、抑制抖振,在动态性能和精度上与传统PI滑模观测器比较有一定提高。Aimed at the enhancement of the speed,stability and robustness of PMSM drive system,fuzzy PI replaced the traditional PI based on the fuzzy control theory,speed and rotor position signal were extracted from counter electromotive force,completed the rotor position detection of PMSM.A Matlab platform was built to validate this method,the experimental results show that the fuzzy PI sliding mode observer has strong robustness and to a certain extent,improves the rapid speed,stability,reliability.The system reduces the overshoot and the chattering,improves the dynamic capabilities,performance and accuracy by using the fuzzy PI,compared with the conventional PI SMO.
