中文摘要：

模糊控制器设计简单,不需要建立被控对象的精确的数学模型,并且控制性能优越、鲁棒性强,因而被广泛关注.将模糊控制引入永磁同步电机（PMSM）的运行控制,提高系统的运行稳定性是一个具有研究价值的领域.将模糊PI方法引入PMSM的位置环控制,分析模糊控制系统的构成以及实现方法.利用MATLAB/Simulink进行系统建模,并对加负载和去负载两种PMSM运行状态进行仿真.仿真结果验证了所搭建系统的正确性及可行性,并通过与常规三闭环PI控制的PMSM系统对比,表明在位置环采用模糊PI控制能更好的降低负载扰动对系统的影响,提高系统性能.

英文摘要：

The fuzzy control system of permanent magnet synchronous motor （PMSM） , which can improve opera tional stability of the system, is obviously of great researching value. The fuzzy PI method was introduced to the PMSM position loop control system, and basic theory and realization method of fuzzy control system have been investi gated. A simulation model of the system based on Matlab has been constructed, and the operation results with or without load have obtained. The correctness and feasibility of building systems has been verified with simulation re suits. And a better performance can be obtained by the adoption of a control system with the fuzzy PI control loop compared with the conventional system.
