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。

After the summary of the domestic and foreign correlation researches, we had an investigation on 413 Junior Middle School students with the test anxiety self-estimate scale and the self-description questionnaire, through the data analysis, we got the following conclusions: 1. There is no significant difference between genders and grades of the Junior Middle School students'overall self-concept. However, the factors of self-concept: math, appearance, honest, language, the relation of the same sex,and the relation of the different sex have significant differences on sex dimensions. Appearance, language and self-concept have differences in grades.

在对国内外相关研究作了综述的基础上，本研究采用了考试焦虑自我调查量表和自我描述问卷，对413名在校初中生进行调查，通过数据分析得出如下结论： 1、初中生总体自我概念在性别和年级上不存在显著差异，但自我概念中的数学、外貌、诚实、言语、同性、异性等因子在性别维度上差异显著，外貌、言语自我概念存在年级差异。
