Design of high power switched reluctance motor controller

Abstract

This paper takes the high power Switched Reluctance Motor (SRM) as an example, and designs the control system of the SRM according to the structure and operation characteristics of the high power SRM. The control system takes STM32 MCU as the core, and is composed of driving circuit, current detection circuit and protection circuit. The control methods commonly used in SRM include current chopper control (CCC), voltage chopper control (VCC) and Angle position control (APC). In addition, PI closed-loop control strategy is used to optimize the system performance, which verifies the feasibility and stability of the design of the motor control system.
