Linear matrix inequality based robust decentralized stabilization of interconnected fuzzy large-scale systems with parametric uncertainties
基于线性矩阵不等式的参数不确定性关联模糊大系统的分散鲁棒镇定

Robust decentralized stabilization problem for interconnected fuzzy large-scale systems with parametric uncertainties is considered. The parametric uncertainties are unknown but norm-bounded. Based on Lyapunov stability theory and decentralized control theory of large-scale system, sufficient conditions for asymptotic stability of the closed-loop fuzzy large-scale system with decentralized PDC (parallel distributed compensation) fuzzy controllers are given. These DPDC controllers can be found by solutions of the LMI-based sufficient conditions via LMI toolbox in MATLAB software. Finally a simulation example is given to show the validity of the proposed method.
