摘要
对劳斯稳定性判据判定范围进行了再划分,明确地判定出某线性定常系统属于渐近稳定,还是临界稳定,或是发散不稳定。并以具有代表性的一些例题,说明如何判定一个线性定常系统的稳定性的类别,推证出特征方程所有对称于坐标原点互为相反数根的一般表达式。
In this paper, the testing area of Routh Stability Criteron is redivided. Asymptotic stability or critcal stability or divergent unstability of a linear invariant system are clearly judged. Some typical examples are given to illustrate how to judge the stabitity type of a linear invariant system and deduce the general expression for eigenvalues which are symmetic members of the coordinate origin.
