摘要：本文提出了一种新的电流环、转速环双闭环系统的设计方法，该方法减小了经典设计方法小时间常数处理引入的误差，同时通过比例微分单元实现零极点对消，对消掉较大时间常数的极点，然后按照典型Ⅰ型与Ⅱ型系统的设计准则设计系统的调节器。通过实验对比证明，本文提出的设计方法设计的系统具有超调量小、过渡时间快的优点。该方法能够用于对超调、过渡时间要求高的电流环、转速环双闭环系统设计。

Abstract: In this paper, presented a new dualloop system design method about current loop and speed loop. The method reduced error introduced by the classical smalltime constant processing design methods. At the same time, proportion differential element was used to carry out the zeropole point cancellation, and the large time constant of the pole were canceled. Then the regulator of the system was designed according to design criterion of the typical type 1 and type 2 system. Experiment prove the system designed by this method have advantages of small overshoot and fast transition time. So, the method can be used to design dualloop system of current loop, speed loop that have high requirement of small overshoot and fast transition time.
Key words: current loop; speed loop; overshoot; transition time; Zeropole point cancellation
