摘要 研究了一类不确定时滞切换系统的H∞意义下渐近稳定性问题.利用李雅普诺夫函数和凸组合技术及LMI方法,给出了这类系统切换策略的设计方案和在扰动输入w(t)为零的前提下渐近稳定充分条件以及w(t)为非零时具有H∞抗扰动衰减度γ. In this paper,the problem of H_∞ asymptotic stability for a class of uncertain time-delay switched systems is studied.By using Lyapunov function and convex combination technique and LMI (linear matrix inequality) method,a switching law of this class of systems is designed to make the systems be asymptotically stable.A sufficient condition of asymptotic stability is obtained when disturbance equals zero.The systems have performance of H_∞ anti-disturbance attenuation when disturbance doesn′t equal zero.
