摘要
本文研究广义Liénard型系统x。=φ(y)-F(x)y。=h(x,y)-g(x)+e(t)(E)的稳定性行为,获得了所有解正向有界的一系列充分条件和充要条件,以及(E)的解全局吸引的充要条件,推广和改进了文献中的一些结果.
In this paper,a study is made on the boundedness and convergence of the generalized Liénard system :{^. x=φ(y)-F(x)
^. y=h(x,y)-g(x)+e(t) (E)
A series of necessary and sufficient conditions for the solution of (E) to be postively bounded are obtained. Further,results of the solution of (E) to be convergent to the origin are obtained too. Some of the results in the literature are improved and their use is extended.
