DECENTRALIZED STABILIZATION AND OUTPUT TRACKING OF LARGE-SCALE UNCERTAIN SYSTEMS

A method for the design of linear constant decentralized robust contro llers for a class of uncertain interconnected systems is presented in this paper. The uncertainties are assumed to satisfy the general match ing conditions for each decomposed subsystem, and both stabilizing con trol and output tracking control are considered here, In the former, t he uncertainties may be time-varying, and the system can be exponentia lly stabilized, In the latter, with the assumption of time-invariant u ncertainties, the system can approach the constant reference input and reject constant disturbances with a prescribed convergence rate, Copy right (C) 1996 Elsevier Science Ltd.
