多变量鲁里叶系统鲁棒输入、输出稳定性的Gap度量界

The Gap Metric Margin of Robust Input-Output Stability for Multivariable Lur'e Systems

本文讨论了多变量鲁里叶系统鲁棒输入、输出稳定性问题，文中利用Gap度量作为系统中非结构型摄动的测量手段，给出了当系统线性部分的摄动量的Gap度量满足某种估计式，同时非线性部分的扇形斜率也受到某种类型摄动时，闭环系统仍能保持稳定的若干充分条件．

This paper deals With the robust input-output stability of multivariable Lur'e systems. UsingGap metric as the measure of unstructurd uncertainty, the authors give some sufficient conditions for theLur'e systems maintaining input-output stability under the presence of both linear element and nonlinearelement perturbations.
