摘　　要：研究了开关磁阻电机(SRM)的线性数学模型,在此基础上采用变角度的电压PWM斩波控制方式调节电机的转速和转矩.给出实现控制算法的软件设计流程图.用Matlab/Simulink对控制策略进行仿真,验证了电压斩波方式下电机的调速性能;通过Proteus和Keil联调,模拟了在给定的位置输入信号下,利用单片机输出电机的控制脉冲信号,验证了软件设计的正确性.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.
