On the basis of expounding the principle of simplified flux method with energy optimizing, a indirect rotorposition detecting control system of switched reluctance motor based on the simplified flux method with energy optimizing was designed. The current and speed double closed loop control system was adopted. The implementation schemes of the indirect position detecting of energy optimizing flux, the current closed loop control and the speed closed loop control were given. The experiment system of the indirect rotor-position detecting control system of switched reluctance motor based on the simplified flux method with energy optimizing was built. The performances of the system were tested and analyzed. The test results show that the designed system can detect the control signals. And the expected phase current waveforms were obtained by the control system. It is developed as the approach foundation for the design of excellent performance SRD control system.
