摘要
考虑了一类具有输入饱和的不确定非线性关联大系统的分散输出反馈鲁棒镇定问题,利用Riccati方程的方法和矩阵的Moore-Penrose逆给出了这类系统的一种分散输出反馈鲁棒镇定控制器的设计方法.同时,考虑了一类具有输入饱和的不确定非线性相似关联大系统,利用相似系统的结构特点,简化了分散输出反馈鲁棒镇定的条件.
The problem of decentralized output feedback robust stabilization for a class of uncertain nonlinear large- scale interconnected systems with input saturation is considered in this paper. By using Riccati equation approach and matrix Moore-Penrose inverse, a decentralized output feedback controller is designed. Meanwhile, a class of uncertain nonlinear similar large-scale interconnected systems with input saturation is considered. Taking into account the similar structure of the systems, decentralized output feedback robust stabilization condition for the nonlinear similar systems with input saturation is simplified.
