STABILIZATION OF A CLASS OF INTERCONNECTED SYSTEMS USING AGGREGATION MODEL VIA SCHUR APPROACH

ABSTRACT An output feedback controller based on the aggregation model via Schur approch is presented. Equivalent aggreation models for global and each decoupled subsystem are obtained via Schur decomposion technique in order to generate global and local output feedback control signals. The effect of sub-sysyem state interactions is reduced by employing a global signal while the transient response of the system is regulated using a local control signal. Stability analysis of the proposed control scheme is discussed. The effectiveness of the proposed control scheme based on the aggregation model is studied by considering an interconnected power systems.
