状态和控制输入不确定时滞系统基于观测器的鲁棒H_∞控制

Robust Observer-based H_∞ Control for Time-delay Uncertain Systems in State and Control Input

研究一类同时存在状态和控制输入不确定性的时滞系统基于观测器的鲁棒Ｈ∞控制问题。系统的不确定性参数是时变的，但其结构已知。通过构造观测器并利用观测器状态进行反馈控制，使系统不仅鲁棒镇定，而且具有一定的Ｈ∞性能。

This paper deals with the problem of robust observer-based H ∞ control for time-delay uncertain systems in state and control input. The uncertainties are time-varying but with confirmed structure. Based on the observer states, a controller is proposed to stabilize the uncertain time-delay systems. And it can also guarantee H ∞ properties. The controller can be obtained by solving two AREs.
