摘　　要：研究一类含非线性扰动的不确定中立型时滞切换系统的时滞依赖指数稳定性,时滞项为时变时滞.利用平均驻留时间方法和自由权矩阵方法,给出了切换中立时滞系统时滞依赖指数稳定的充分条件,并设计状态反馈控制器,使闭环系统在一定切换策略下指数稳定,最后通过仿真算例验证结果的正确有效性.The delay-dependent exponential stability of uncertain switched neutral systems with time-varying delay and nonlinear perturbations is concerned.A sufficient condition for delay-dependent exponential stability of switched neutral systems is presented by using average dwell time method and free weighting matrix method.Stabilizing state feedback controllers which can guarantee the delay-dependent exponential stability of closed-loop systems under a class of switching laws are designed.Finally,a numerical example is given to show the effectiveness of the results.
