针对状态不可测的切换模糊时滞系统,根据平行分布补偿算法(PDC),设计了切换模糊观测器和反馈控制器,应用共同Lyapunov函数方法使观测误差系统在任意切换下渐近稳定,应用多Lyapunov函数方法。使系统状态在设计切换律下渐近稳定,并给出了时滞相关的切换模糊系统渐近稳定的矩阵不等式条件.仿真结果表明结论的有效性.
The stabilization problem is addressed for a class of switching fuzzy time-delay systems, For the non- measurable states, a switching fuzzy observer and a feedback controller are designed based on the parallel distributed compensation(PDC) method. Asymptotic stability of the observed error system is then obtained by the common-Lyapunov-function method. A switching law is also designed by the multiple-Lyapunov-function method to guarantee the asymptotic stability of the systems. Delay-dependent conditions for asymptotic stability of the switching fuzzy systems are obtained in terms of matrix inequalities. Finally, simulation results show effectiveness of the design method.
