摘　　要：针对带有时变时滞和数据包丢失的离散网络切换控制系统,提出在任意切换信号下的闭环故障检测和控制器协同设计策略;基于平均驻留时间和李雅普诺夫(LKF)方法,给出并证明离散切换时滞动态系统指数均方稳定且具有满意的H∞性能指标的充分条件;将离散网络切换时滞系统的控制器和故障检测滤波器的参数求解转化为可行的凸优化问题,确保残差和故障估计误差尽可能小.仿真实验结果验证了所提出方法的有效性.A fault detection（FD） and control co-design scheme is studied for discrete-time switched systems with timevarying delays under an arbitrary switching signal in a network communication. By using the average dwell-time scheme and a Lyapunov–Krasovskii functional（LKF）, a delay-dependent sufficient condition is developed to ensure the resulting error system to be exponentially stable in the mean-square sense with an optimized H∞ disturbance attenuation level. The solution of the parameters for the fault detection filter and controller co-design are characterized in terms of the feasibility of a convex optimization problem. A numerical example is given to illustrate the effectiveness of the proposed method.
