Robust H∞ control for uncertain systems with time-varying delay
-
摘要: 基于魯棒二次穩定性理論,采用線性矩陣不等式方法,研究了具有時變狀態時滯的不確定系統的魯棒H∞控制問題,給出了對所有允許不確定性,被控對象滿足H∞范數界γ約束下魯棒二次穩定的一個充分條件.通過求解一個線性矩陣不等式,即可獲得H∞狀態反饋控制器.Abstract: Based on the quadratic stability theory, the problem of robust H∞control for time-delay systems with time-varying uncertainties was dealt with by using the linear matrix inequality approach. A sufficient condition for the systems to be quadratically stable with an H∞-norm bound γ was presented for all admissible uncertainties. By solving a linear matrix inequality, the H∞ state feedback controller was obtained.
