摘　　要：直流电机具有优异的起动、调速及制动性能在直流调速领域应用广泛.研究了两种直流PWM-M调速系统,分析了它们的工作原理,并在Matlab/Simulink中对它们进行建模与仿真,最后对仿真结果进行了比较分析.仿真结果表明双极式PWM-M调速和受限单极式PWM-M调速系统都具有优异的动静态特性,它们均能实现直流电机的正反转,而且可以实现电机的无极调速.区别在于受限单极式PWM-M调速系统的稳定性比双极式PWM-M调速系统更加好.DC motor with excellent starting, speeding and braking performance is widely used in the field of DC regulating speed. Two kinds of regulating speed control system for DC PWM-M are studied, and their working principles are analyzed, and the modeling and simulation of them are carried out based on Matlab/Simulink. Finally, the simulation results are compared and analyzed, and the simulation results show that the control system of bipolar PWM-M regulating speed and the restricted unipolar PWM-M regulating speed have excellent dynamic and static characteristics, and they can all realize forward and reverse, and can also realize stepless regulating speed for DC motor. The difference is that the stability of the restricted unipolar PWM-H regulating speed system is better than the bipolar PWM-M regulating speed system.
