| 摘 要： | 利用多Lyapunov函数和共同Lyapunov函数方法，研究一类不确定离散切换模糊控制系统的鲁棒输出反馈控制问题。在状态矩阵和控制矩阵具有不确定性的条件下，通过系统输出重构状态方程，并设计控制器及切换律，给出了使系统渐近稳定的一组LMI条件。最后通过仿真例子验证了设计方法的有效性和可行性。

| Abstract: | The problems were investigated on robust output-feedback control for a class of uncertain discrete-time switched fuzzy control systems by using multiple Lyapunov function and common Lyapunov function.Both the controller and the switching rate were aU designed under the conditions that the state matrix and the control matrix were all of uncertainties,herein with state equation reconstructed by system output.The LMIs sufficient conditions of the asymptotic stability of the uncertain switched Fuzzy control systems were presented.Finally an illustrative example was given to demonstrate the feasibility of the proposed approach in design. |
