In more competitive markets, companies tend to innovate in good times and bad, explains Yuko Kawamoto of Waseda University, but in Japan it often takes a downturn to get companies and consumers to try new things. During Japan's "lost decade" in the 1990s some companies flourished by introducing high-quality products at low prices.

据早稻田大学的Yuko Kawamoto解释，在更具竞争性的市场中，公司倾向于在经济繁荣和衰退时进行创新，但在日本，常常是经济下行时才会使公司和消费者尝试新的东西。20世纪90年代在日本"失落的十年"期间，有些公司通过低价引入高端产品而繁荣兴旺。

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.
