-
摘要: 基于二次穩定性理論,研究了不確定離散時滯系統的魯棒H∞控制問題.采用線性矩陣不等式的方法,討論了有記憶狀態反饋魯棒H∞控制問題,得到了確保魯棒H∞控制器存在的充分條件和H∞狀態反饋控制器的設計方法.最后舉例說明了該方法的正確性.Abstract: Based on the quadratic stability theory, the robust H∞ control problem for uncertain discrete-time systems with timedelay was deal with. The problem of robust H∞ control with memory state feedback was discussed by linear matrix inequality approach. The sufficient condition for a robust H∞ controller was derived. An H∞ state feedback controller was designed and the controller could be solved by one LMI. An illustrative example was presented to prove the correctness of this method.
