Some Stability Criteria of Nonlinear Differential-Algebraic Systems
非线性微分-代数系统稳定性的几个判据

In this paper, the stability problem of nonlinear differential algebraic systems is investigated. Some stability and unstability criteria of nonlinear differential algebraic systems are given by using the partial derivative matrices of nonlinear functions. The calculating procedure presented is straight forward and the criterions can be easily applied. At last, an example is given to illustrate the effectiveness of the algorithm.
