Abstract
In this paper, the H∞ control synthesis problem for a class of large-scale systems with multi-modes that are called large-scale switched systems is addressed. By introducing the concept of decentralized switching signal and the relevant decentralized average dwell time, the asymptotic stability and weighted ℓ2 gain performance are investigated. It should be noted that the decentralized switching covers general switching cases for large-scale switched systems, namely, it admits both time-dependent switching signal and arbitrary switching signal blended in the decentralized switching. Then, on the basis of the analysis results, the decentralized weighted H∞ control scheme including state feedback controller gains and switching signals is studied. Several design algorithms are proposed to meet different controller design problems. Finally, numerical examples are provided to illustrate theoretical findings within this paper.
