In this paper, a new method used to deal with the motion ability is studied deeply based on Routh-Hurwitz Criterion. The advantage of this kind of analysis method consists in the fact that after establishing the equation in differential calculus for the motion system, there is no need to know a root of the equation, if you know the root signs, you can judge the zero solution stability of the system.
本文利用劳斯-赫尔维茨判据(Routh-Hurwitz Criterion)对机械系统中离心转速调节器的运动德定性进行了分析,这种分析方法的优点就在于:建立系统运动微分方程的特征方程后,不必求解特征方程的根,只需知道根的符号就可判断系统的零解稳定性。
