摘要开关磁阻电动机（SRM）的结构比较简单，其制造的成本不高，调速的范围宽，整个调速的效率比较高。开关磁阻电机控制系统（SRD）可靠性高，这些年来得到较多的推广。开关磁阻电机的定子与转子都是凸极构成双凸极结构，这样就使电动机在工作时出现很大转矩脉动，从而产生较大的噪声。从其控制方案入手，能够减小电机在工作的时候产生的转矩脉动，以及其噪声。

本文首先分析开关磁阻电机的基本结构以及其运行方式，从（8/6）结构的开关磁阻电机入手，推导开关磁阻电机的磁链方程、转矩方程，再以其电机特性得出（8/6）结构开关磁阻电机控制的空间电压矢量。对SVPWM控制技术的基本的原理进行详细的分析讲解，进行SVPWM算法。设计系统中相应的硬件以及软件，实现对开关磁阻电机的矢量控制，达到设计要求。最后通过MATLAB仿真软件进行仿真，构建仿真模块，实现SVPWM对开关磁阻电机的矢量控制，得出相应的仿真波形，并对相应的波形进行一定的分析。

总结整篇论文主要的工作内容，分析本设计重点，研究中解决的难题。分析开关磁阻电机的发展前景，结合研究过程出现的问题给出相应的思考。对整个设计进行一个总体的评价，找出设计中的优缺点，最终是对开关磁阻电机控制系统的展望。77342

Switched Reluctance Motor Control System Design

Abstract The structure of switched reluctance motor (SRD) is relatively simple, and the manufacturing cost is low; the speed regulation performance is good; the speed regulation range is wide; the speed regulating range has high efficiency。 Switched reluctance motor control system (SRM) has high reliability, and it has been widely used in recent years。 The stator and the rotor of the SRD is convex pole which is doubly salient structure, which makes the motor at work are the large torque ripple, resulting in larger noise。 Starting from the SRD control scheme can reduce the torque ripple of small RD in working, and the noise。

Firstly, understanding of SRD basic structure and its operation mode, starting from the SRD (8/6) structure, derivation of SRD flux equation and torque equation, to the motor characteristics that (8/6) structure of SRD control of space voltage vector。 SVPWM control technology to the basic principles of a detailed analysis to explain, to achieve SVPWM algorithm。 The corresponding hardware and software of the system is designed to realize the vector control of the switched reluctance motor, which can meet the design requirements。 Finally through the MATLAB simulation software to simulate, build the simulation module, SVPWM to achieve the vector control of switched reluctance motor, the corresponding simulation wave forms, and the corresponding waveform analysis。

Summarize the main work of the thesis, analyze the key points of the design, and solve the problems in the research of simple action。 The development prospect of switched reluctance motor is analyzed, and the corresponding thinking is presented in this paper。 An overall evaluation of the whole design, find out the advantages and disadvantages of the design, and finally to the control system of switched reluctance motor。
