To achieve high-performance PMSM position servo system, advanced control scheme, which is static precision, transient responses and self-adaptation and anti-disturbances, is needed in practice. Based on the analysis on the features and control principles of PMSM, this thesis established its math model using id=0 vector control method. Three close loops control system, which includes current loop, velocity loop and position loop, was built up. For position loop, the main feedback loop, we chose a new adapted-fuzzy CMAC intelligent controller, which includes self-learn ability of neural net and quick response merit of fuzzy controller. Finally, the author simulates PMSM position servo system by the simulink of matlab, an advanced computer simulation tool.

本文对PMSM的控制机理和特性作了较为深入的分析；建立了PMSM的数学模型，并采用了id=0的矢量控制策略；对控制系统组成及控制方式作了分析和比较，在此基础上建立了电流环、速度环和位置环的三闭环控制系统，对作为反馈主回路的位置环采用了模糊CMAC神经网络控制方法，该方法兼具模糊控制器的快速性和神经网络的自学习能力；构建了针对PMSM位置伺服系统的模糊CMAC控制器结构及其相应的算法；利用先进的计算机仿真工具（Matlab下的Simulink）对所提出的控制策略进行了数字仿真和分析；仿真和实验结果表明本文所提出的控制策略对PMSM位置伺服系统进行控制具有良好的鲁棒性能和快速性。
