不确定线性内互联大系统的分散鲁棒H∞控制

讨论含有界不确定性的线性内互联大系统，通过分散状态反馈和分散动态输出反馈的鲁棒Ｈ∞控制问题，首先给出一个重要引理，然后基于有界实引理分别导出放动态输出反馈的分散鲁棒Ｈ∞控制问题有解的充分必要条件，该条件及其问题的求解等价地转化成一个线性矩阵不等式和双线性矩阵不等式的求解。

Decentralized Robust H Control for Uncertain\= Interconnected Large-scale Systems

This paper investigates the problem of robust H control of interconnected large-scale systems with uncertainty, via decentralized state feedback and decentralized output feeedback. First, an important lemma is proposed, secondly a necessary and sufficient condition for the existence of a decentralized robust H controller has been presented based on the bounded real lemma. Then, the decentralized robust H control problem is reduced to a feasibility problem of a linear matrix inequality and a bilinear matrix inequality.
