Decentralized robust adaptive control of uncertain nonlinear interconnected large-scale systems
Min Zhang, HU Shou-song · 2008
This article surveys a class of large-scale systems with uncertainties and nonlinear interconnected items in its subsystems, and presents a kind of decentralized robust adaptive controller. First, a kind of robust Hinfinoutput feedback controller is designed for restraining the external disturbances, and then a dynamic structure adaptive neural network is introduced, which can eliminate the uncertainties and nonlinear interconnected items between subsystems, so that every subsystem is independently asymptotical stable and the whole large-scale system is consequently decentralized stable. The simulation results demonstrate the efficiency of the proposed methods.
