摘　　要：通过构造切换Lyapunov函数以及不等式方法,获得了线性脉冲离散切换系统指数稳定性的充分判据,以及具有非线性不确定扰动项的脉冲离散切换系统的指数稳定性的充分判据,最后通过数值仿真验证了所得结论的有效性。Through switching Lyapunov and inequality methods, the exponential stability for impulsive switched discrete linear system and impulsive switched discrete system with uncertain perturbations is studied.New sufficient conditions of exponential stability of these systems are derived.Finally, a numerical example was given to illustrate the validity of the results.
