摘　　要：通过修正Lyapunov函数设计出新的复合控制器,改进了线性时滞不确定系统的可镇定性.实例仿真结果证明,系统中时滞微分的增加对系统的可镇定性的影响比改进前大大地减小.In this paper, a new compound controller is designed based on modified Lyapunov function. The stabilization of linear unceritain timedelayed systems is improved. It is shown that our result is much less conservation in this paper when the size of derivation of the time delay increases in the systems. this result can be proved in the following examples.
