摘　　要：介绍了直流电机的PWM控制原理,按照Avalon总线接口规范设计了PWM模块,给出了读操作、写操作、设定PWM周期的程序,所产生的PWM信号的占空比、周期均可数控,用软件实现直流电机的PWM控制。The PWM control principle of DC motor was introduced. A PWM module was designed in accordance with the criterion of Avalon bus, and the programs for reading, writing and setting the period of PWM signal were given. It is indicated that duty cycle and period of PWM signal can be digitally controlled, that PWM control of DC motor can be realized.
