【Abstract】 The Switched Reluctance Drive (SRD) system possesses good capabilities of adjusting speed, and attracts more and more attention .In this article, the Switched Reluctance Control system is designed based on DSP TMS320F240.This paper introduces basic construction and development of SRD, and describes characteristics and work principle of SRM. The characteristics and choice procedure of IGBT are explained very carefully. Getting change phase logic of control system from H type power circuit, analyzing control strategy of SRM in details, and choosing two kinds of control methods which fit for this system: voltage chop wave control and low speed current chop wave control.Subsequently the development of DSP is presented and the module units of the TMS320F240 used in this paper are introduced. Designing hardware circuits and software for control system based on the TMS320F240.Hardware circuits mainly include low speed current chop wave, current detection circuit, comprehensive logic circuit etc. In order to reduce cost, the control system adopts GAL device, the modular programming methods are adopted to attain versatility and readability, Software include PWM subroutine, measure subroutine, PI subroutine etc. During the course of designing hardware and software, the measure of Anti-interference is taken here, and make the control system possess reliable Anti-disturbance ability. Finally through debugging control system and testing the waveform of control system, the author have preliminary understanding to comprehensive capability of the control system. The final section gives the conclusion and envisions.更多还原
