摘要
考虑一类带模有界时变不确定的非线性系统鲁棒Ｈ∞控制问题．讨论其带内部稳定的状态反馈及输出反馈鲁棒Ｈ∞控制问题可解的充分条件．结果表明，带模有界结构的时变不确定非线性系统，其鲁棒Ｈ∞控制问题可以转化为一确定的非线性系统的Ｈ∞控制来解决，从而可由－Ｈａｍｉｌｔｏｎ－Ｊａｃｏｂｉ－Ｉｓａａｃｓ微分不等式的可解性来讨论．
The robust H∞ control problem for nonlinear uncertain systems with norm-bounded time-varying uncertaintties is considered. The sufficient conditions which the robust H∞ control problem with internal stability is solvable by state feedback and output fedback are given. The results show that for nonlinear uncertain systems with norm-bounded time-varying uncertainties, the robust H∞ control problem can be converted into H∞ control problem for a certain nonlinear systems. furthermore. into solvability of an Hamilton-Jacobi-Isaacs differential inequalities equations.
