摘要
研究了不确定广义模糊系统鲁棒H∞状态反馈控制器和动态输出反馈控制器设计问题。在E确定其它系数矩阵均存在不确定性情况下,给出鲁棒模糊H∞状态反馈控制器和动态输出反馈控制器存在的充分条件。鲁棒H∞状态反馈控制律的设计可能通过求解线性矩阵不等式得到,而动态输出反馈鲁棒H∞控制器可通过定义新变量得到,所求控制器使闭环系统对所有的不确定性稳定且满足H∞性能指标γ。
The problem of robust H∞ fuzzy state feedback and dynamic output feedback control for uncertain fuzzy descriptor systems is discussedIn the case that timevarying uncertainties are in all parameter matrices except E,sufficient conditions for the existence of fuzzy state feedback and dynamic output feedback robust H∞ controllers are given in terms of LMIThe fuzzy state feedback control law can be constructed directly based on the solution of LMIFuzzy dynamic output feedback control law can be obtained by defining new variblesThe robust H∞ control laws guarantee that the closedloop system is admissible as well as satisfying a prescribed norm bounded constraint for all admissible uncertainties
