ON DECENTRALIZED NON-LINEAR FEEDBACK STABILIZATION OF INTERCONNECTED SYSTEMS

Abstract The paper presents a simple on-line approach for designing state feedback controllers for a class of linear interconnected and parameter varying systems. The stability of the decentralized control system is demonstrated using the notion of eventual stability introduced by Lasalle and Rath. The stability of the system subjected to disturbances is also investigated. The policy is stable, easy to implement and processes design freedom for shaping the systemʼs dynamic response. The system may be stable, unstable and with unknown parameters. The control design need no a priori information. The results are illustrated numerically.
