摘　　要：对于一类不确定时滞的连续切换模糊系统,研究其静态输出反馈控制问题.利用多Lyapunov函数方法及切换策略,使得相应的闭环系统渐近稳定,同时设计可以实现系统全局渐近稳定的切换律.提出了确保该系统可通过输出反馈鲁棒镇定的充分条件,并将该充分条件转化为具有较强可解性的线性矩阵不等式(LMI)问题.最后用MATLAB软件对系统进行仿真,验证结论的可行性与有效性.The static output feedback control problem is addressed for a class of uncertain time-delay continuous switched fuzzy systems. Using multiple Lyapunov function method and switching law, the relevant closed-loop system is asymptotically stable, with the switching law designed to implement the global asymptotic stability. The sufficient conditions to ensure the output feedback asymptotically stable output feedback control of closed-loop system are studied. The sufficient condition is transformed into Linear Matrix Inequality （LMI） problem which are more solvable. Finally, a numerical simulation example is employed to illustrate the effectiveness and the convergence of the design methodologies.
