Title: Decentralized Observer Based H8 Decentralized Control for Interconnected Systems
Authors: S. DHBAIBI and A.S. TLILI and N. BENHADJ BRAIEK
Abstract: This paper presents an approach of H8 decentralized tracking control design with decentralized observer for large scale interconnected systems. The proposed control structure is developed to guarantee the asymptotic stability of the global system, to improve its performances by using a modified H8 criterion and to ensure the tracking of a reference model with the minimization of the external disturbances effect. Moreover, the synthesized controller includes a decentralized observer which allows the reconstruction of the non measurable state variables of each subsystem. The determination of the control and observer gains is derived by means of an optimization problem which is formulated in terms of linear matrix inequalities (LMIs). Simulation results on a three interconnected machine power system are presented to highlight the performances of the proposed control scheme.
