讨论了单个控制器同时镇定一组时滞奇异系统的问题。通过引入Lyapounv-Krasovskii泛函,给出所设计的同时镇定控制器的充分条件,保证了奇异时滞闭环系统的正则、无脉冲、稳定且具有H¥性能。利用基于观测器的状态反馈和状态反馈控制相结合的方法得到闭环时滞奇异系统同时H¥控制的充分条件,明确地给出了输出反馈控制律的表达式。所得控制器可由一组线性矩阵不等式求解得出,避免了矩阵分解。最后,由仿真算例说明该方法的可行性。
討論瞭單箇控製器同時鎮定一組時滯奇異繫統的問題。通過引入Lyapounv-Krasovskii汎函,給齣所設計的同時鎮定控製器的充分條件,保證瞭奇異時滯閉環繫統的正則、無脈遲、穩定且具有H¥性能。利用基于觀測器的狀態反饋和狀態反饋控製相結閤的方法得到閉環時滯奇異繫統同時H¥控製的充分條件,明確地給齣瞭輸齣反饋控製律的錶達式。所得控製器可由一組線性矩陣不等式求解得齣,避免瞭矩陣分解。最後,由倣真算例說明該方法的可行性。

The problem of simultaneously stabilizing a collection of singular time-delay systems witha single controller was considered.By introducing Lyapunov-Krasovskii functional,gave a sufficient condition,which guarantees the singular closed-loop system regular,impulse-free,stable and withH¥performance.The sufficient condition of simultaneousH¥controller sufficient condition was derived via applying the state observer and observer-based state feedback to singular closed-loop systems.An explicit expression of the desired output feedback control law was also given.The obtained criterions were formulated in terms of linear matrix inequalities(LMI) involving no decomposition of system matrices.Finally,a numerical example is provided to demonstrate the feasibility of the proposed method.
