Operation on overspeed

This paper studies existing question of the system,including the saturable limita-tion and the speed overshoot during the staring process,then different resolutions are proposed.

本文分析了转速—电流双闭环直流调速系统采用常规PI调节器进行速度控制时存在的输出限幅和转速超调问题,并给出了解决超调问题的各种控制方案。

However,the speed overshoot consequentially exists during the starting process.

双闭环直流调速系统的速度调节器采用常规的比例积分(PI)调节器时,起动时必然存在转速超调。
