基于观测器的H∞鲁棒次优性能回复设计

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.

A Performance Recovery Approach to H∞ Robust Sub-optimal Control Via Observer

This paper proposes a performance recovery approach to H∞ robust sub-optimal controller design problem for plant with structured uncertainty. It is shown that if there exists such a state feedback gain matrix that the closed loop system satisfies H∞ robust sub-optimal performance and the state is not measurable, then one can introduce a high gain observer such that H∞ robust sub-optimal performance of the closed loop system arbitrarily approaches to the performance achieved by the state feedback.
