Decentralized state feedback robust H ∞ control using a differential evolution algorithm
International Journal Of Robust And Nonlinear ControlPeer ReviewedHarno Hendra G. +12012Journals
SUMMARY This paper presents a new method to synthesize a decentralized state feedback robust H ∞ controller for a class of large‐scale linear uncertain systems satisfying integral quadratic constraints. The decentralized controller is constructed by taking only block‐diagonal elements of a nondecentralized state feedback controller and treating neglected off‐diagonal blocks as uncertainties. A solution to this controller synthesis problem is given in terms of a stabilizing solution to a parametrized algebraic Riccati equation where the parameters are obtained using a differential evolution algorithm.Copyright © 2012 John Wiley & Sons, Ltd.
