摘　　要：在网络环境下,考虑网络传输时延和外界干扰输入的影响,基于模型依赖平均驻留时间方法研究一类不确定模糊时滞系统的切换H_(∞)控制问题。首先,基于模型依赖平均驻留时间方法,提出系统状态反馈控制器及切换策略的设计方案。进一步,通过多Lyapunov函数方法求解一组线性矩阵不等式,给出满足系统指数稳定且具有H_(∞)性能指标的充分条件。最后,通过数值仿真例子验证所提方法的有效性和可行性。In the network environment,considering the influence of network transmission delay and external disturbance input,the switched H_(∞) control for a class of uncertain fuzzy time-delay systems is studied based on the model-dependent average dwell time method.Firstly,the design scheme of the state feedback controller and the switching strategy is proposed based on the model-dependent average dwell time method.Furthermore,a set of linear matrix inequalities is solved by multiple Lyapunov functions method,the sufficient conditions are provided to satisfy the exponential stability of the system which has H_(∞) performance index.Finally,a numerical simulation example demonstrates the effectiveness and feasibility of the proposed method.
