摘要
利用变量梯度法来构造一类三阶非线性系统的李雅普诺夫函数,通过对构造的李雅普诺夫函数进行讨论,得出该系统的零解稳定性.
In this study,we have constructed Lyapunov function of a class of three-order nonlinear system by means of variable gradient method.Based on the discussion of Lyapunov function constructed,we have proved the stability of zero solution of this system.
