DESIGN OF ROBUST ADAPTIVE REGULATORS FOR LARGE-SCALE SYSTEMS

This paper presents a new robust adaptive control scheme to solve the regulation problem of large-scale systems. We consider linear large-sc ale systems which can be decomposed into single-input single-output in terconnected subsystems, with unknown and/or slowly time-varying param eters, and described by discrete state-space models. We propose a dece ntralized and partially decentralized regulators on the basis of the s tate-feedback approach. Sufficient conditions, under which the overall system can be asymptotically regulated, are established by utilizing the Lyapunov function. The performance of the developed results is eva luated by numerical simulation.
