| The paper reviewed the development of switched reluctance drive. According to the fields where SRD was applied,the SRM s torque analysis,current analysis and run-way analysis were discussed. And also the control method of SRM s controller,design theories and ways of controller ,power converter and adjuster were studied.The paper involved SRM s maths model,velocity-control theory and feedback-signal-check technique. According to SRD s main technical demand,SRM s raw data and SRM s control theory ,the main system was divided into several modules. Based on the modules,by selecting proper components and calculating right parameters,in parallel with the sample machine s experiments,the cotroller s design was completed and the system completely meet the demands. In the end ,ways without sensors were discussed.
