摘要
机床电力拖动系统采用集成电路实现脉宽调制方式调速用IGBT管驱动电动机。以SG15 2 5集成电路为核心 ,电压负反馈代替转速反馈 ,形成闭环控制 ,比例积分调节器实现无静差调速 ,系统具有良好的性能。
This article presents the application of IGBT-PWM regulating speed system in machine tool's electric drive. In the system, integrated circuit SG1525 used as control unit, voltage feedback instead of speed feedback, PI regulating no steady\|state error. So it has a good dyramic and steady performance.
