中文摘要： 双凸极永磁同步电机（DSPM）由于结构简单坚固、容错性好、运行可靠、功率密度高的众多优点，在很多领域得到重用。但是DSPM电机的特殊结构，导致了非正弦波特性，进而直接影响了电机的动态性能并且增加了转矩脉动。由于非正弦波电机的永磁体磁链与电感具有相同的变化率，使得常规的矩形电流和三相正弦电流难易满足消除转矩脉动的要求，因此，本项目以非正弦齿极DSPM电机为研究对象，以消除转矩脉动提高电机运行性能为目的，以电磁场有限元分析、遗传算法、快速傅里叶变换以及矩阵论等为技术手段，展开对DSPM电机控制算法和控制策略的研究，重点解决所遇到的若干关键性科学问题：1）非正弦波电机转矩脉动的形成规律；2）探索消除非正弦波电机转矩脉动电流形式；3）非正弦波电机解耦控制策略与算法的研究。最后，利用MATLAB软件和RT-LAB半实物仿真平台对电机模型和控制算法进行验证与测试.

英文摘要： Doubly salient permanent magnet synchronous machine (DSPM) is widely used in many fields because of its numerous advantages such as: simple structure, good fault-tolerance, reliable operation, high power density. But due to the special structure of the DSPM machine, it has special non-sinusoidal waveform characteristics which affect the machine dynamic performance and increase the torque ripple. The rectangular current and classical three phase sinusoidal waveform current cannot eliminate the torque ripple on account of the same variation of the permanent magnet flux and the inductance of the non-sinusoidal waveform machine. As a result, one non-sinusoidal waveform tooth-DSPM machine is regarded as the research object in this project. For the sake of eliminating the torque ripple and improving the machine dynamic performance, we will use electromagnetic field finite element method, genetic algorithm, fast Fourier transform and Matrix theory to research on the control algorithm and control strategy. The encountered scientific problems which need to be solved are: 1) the formation of the non-sinusoidal waveform machine torque ripple; 2) explore the current waveform to eliminate non-sinusoidal waveform machine torque ripple; 3) non-sinusoidal waveform machine decoupling control strategy and control algorithm research. Finally, using MATLAB and RT–LAB to verify the machine model and control algorithm.
