The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided. Because of the full use of the abundant peripheral resources of DSP, it comes to the aim simplifying the circuit structure and heightening the reliability. In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.

Because of the off-phase motor running to recognize the harm caused by different fault in the implementation phase of the motor protection have had two different views: that the broken phase to the electrical damage caused by overheating point of view to the implementation of the motor overheating protection or inverse-time characteristics of overcurrent protection, thermal relays the resulting program, thermal resistance package with over-current fault protection program delay, and other programs; that the break caused by phase to the motor windings high-voltage breakdown back-EMF's view of Open-phase protection program to take instantaneous action, and some electronic-type protectors available.

由于对断相运行给电机造成的危害认识不同，因此在对电机实行断相保护时产生了两种不同的意见：认为断相给电机造成过热损坏的观点要对电机实行过热保护或过流反时限特性保护，由此产生了热继电器方案、热敏电阻方案、断相过流延时保护方案以及其他一些方案；认为断相给电机绕组造成高压反电势击穿的观点，对断相采取瞬时动作保护方案，于是一些电子式保护器问世。
