Autonomous Decentralized Control

Abstract

A decentralized control law is called autonomous if the resulting closed-loop interconnected system is connectively stable, that is, the system remains stable despite structural perturbations whereby subsystems are disconnected and again connected in an unpredictable way during operation. The objective of the paper is to propose an LMI scheme for design of autonomous decentralized controllers and observers for output control of complex systems. An interesting feature of the proposed observer-based controllers is that they do not impose any communication overhead since only the locally available output information is required.
