论文摘要
本文提出了一种代数技术,以计算无刷直流电动机(BLDCM)速度控制器的控制循环中可以接受的最大时间延迟,然后封闭环路响应变得不稳定。使用最近提出的时间延迟稳定性分析方法,我们得出了BLDCM速度控制器的准确稳定性条件。应用新方法的结果表明,在BLDCM机械时间常数的数量级以非常快的响应调整PI控制器,导致时间延迟显着影响系统稳定性。
This paper presents an algebraic technique to compute the maximum time-delay that can be accepted in the control loop of a Brushless DC Motor (BLDCM) speed controller before the closed loop response becomes unstable. Using a recently proposed time-delay stability analysis methodology, we derive accurate stability conditions for the BLDCM speed controller. The results of applying the new method show that tuning the PI controller for very fast response in the order of magnitude of the BLDCM mechanical time constant cause the time-delay to significantly affect the system stability.
