It is very important to detect the accurate rotor position of switched reluctance motor (SRM) for a high-performance switched reluctance motor drive. And, there are two main factors to influence SRMs rotor position detection, which are the accuracy of the position signal and the controllers real-time response. It cant meet the accuracy requirements to detect shaft position information by opto-couplers, so absolute encoder is used to produce the high-precision rotor position signal. Moreover, the all-digital controller based on DSP and CPLD achieves the real-time detection and applications of high-precision rotor position signal on SRM, with their strong ability on data processing and hardware logic describing. Due to adopting high-precision rotor position detection and control, it carries out successfully and improves the system performance. The experimental results show that the design is reliable and effective, which has great significance for the establishment and realization of high-performance SRM drive.
