Analysis and Application of Control Strategy for Switched Reluctance Drive with Position Sensor

Switched reluctance motor (SRM) has simple structure, low power consumption, stable performance and high efficiency, and has a good application prospect. Its rotor is composed of silicon steel sheets overlapped with each other, and each phase winding works independently. In this paper, the position signal and phase inductance of the SRM position sensor are analyzed. Based on the STM32 design of the SRM speed control system, three control modes of current chopping control (CCC), voltage chopping control (VCC) and angular position control (APC) are realized in different moment regions. In addition, closed-loop PI control is adopted to ensure stable and reliable operation of the system. In this paper, the three-phase 6/4-pole SRM is taken as an example to verify the feasibility and stability of the system design. And last, three-phase 6/4-pole SRM is taken as an example to test three control strategies of the system.
