一类具有两个非线性项的四阶非线性系统的稳定性

stability of a Class of Fourth-order Nonlinear System with Two Nonlinear Terms

利用"类比法"构造了一类四阶非线性系统的Lyapunov函数,给出了该系统零解稳定性的充分条件.

This paper constructs a Lyapunov function of a class of fourth-order nonlinear system by the use of comparison method, and derives the sufficient conditions for the stability of the trivial solution to the system.
