A linear mathematical model of SRM is studied, and on this basis the voltage PWM chopper control with variable angle is adopted to control the speed and torque ,.The flow chart of the software design is given to achieve control algorithm. The control algorithm is simulated by Matlab / Simulink, proving the motor＇s speed performance in the voltage chopper mode. Given an input signal of the position sensor, Proteus and Keil are used to make the MCU output the pulse signal to control the motor, verifying the correctness of the software.
