【摘要】 提出了一种基于状态观测器的Ｈ∞鲁棒次优性能回复设计方案．对于具有不确定性的被控对象，当存在满足给定的Ｈ∞鲁棒次优性能准则的状态反馈阵，且状态不可测量时，引入适当的状态观测器可使闭环系统的Ｈ∞鲁棒次优性能任意接近状态反馈系统．更多还原

【Abstract】 This paper proposes a performance recovery approach to H∞ robust sub-optimalcontroller design problem for plant with structured uncertainty. It is shown that ifthere exists such a state feedback gain matrix that the closed loop system satisfiesH∞ robust sub-optimal performance and the state is not measurable, then, one canintroduce a high gain observer such that H. robust sub-optimal performance of theclosed loop system arbitrarily approaches to the performance achieved by the statefeedback.更多还原
