中文摘要 |
针对一类带有输入时滞和状态时滞的不确定模糊系统, 讨论了其稳定性和H∞鲁棒控制控制器设计问题.根据“Descriptor form”的Lyapunov-Krasovskii 泛函方法, 得到的时滞相关稳定性准则, 使得所设计的控制器能确保闭环系统渐近稳定. 为了使所得的结果具有更小的保守性, 同时还设计了一个凸优化算法. 仿真结果说明本文所提出方法的可行性和优越性. |
英文摘要 |
The H-infinity robust control is addressed for a class of uncertain fuzzy systems with time-delays in both states and control inputs. Using a Lyapunov-Krasovskii functional in “Descriptor form”, we presented the delay-dependent sufficient conditions of stability for the closed-loop system with the designed controller. To be less conservative in design, we employ an algorithm involving convex optimization in designing the state-feedback controller. The example shows the validity of our results. |
