摘要
文章介绍了应用集成脉宽控制器SG3524产生脉冲控制信号,绝缘栅双极型晶体管(IGBT)为功率开关器件,实现直流电动机PWM调压调速。该调速系统以电压负反馈代替转速反馈,形成闭环控制,以比例积分调节器实现无静差调速,具有良好的性能。
The paper introduces a direct current regulating speed system, which adopts intelligence power mold block IGBT, as major return-circuit switch, and integrated circuit SG3524 was used as pulse control unit. It can research PWM regulating speed. In the system, voltage feedback instead of speed feedback, PI regulating no steady-state error. So it has a good dynamic and steady performance.
