关于李雅普诺夫函数的几点注记

摘要

Three definitions and three theorems of Lyapunov function were put forward, and then these definitions and theorems were illustrated with some examples. Finally, under the generalized Hurwitz condition, the "three-step method" was put forward to construct Lyapunov function of nonlinear system.%　　给出了关于李雅普诺夫函数的3个定义和3个定理，举例说明了所得定义和定理的应用，并给出了利用广义霍维茨条件构造非线性系统李雅普诺夫函数的“三步法”。
