On the Subsystem Level Gain Scheduled Controller Design for MIMO Systems

Abstract

This paper presents a unique approach to design in the frequency domain a gain scheduled controller (GSC) to nonlinear Lipschitz MIMO system model. The proposed design procedure is based on the Method of Equivalent subsystems and Integral Quadratic Constraints-Small Gain Theory. The feasible design procedures provide a subsystem equivalent frequency characteristic and frequency design method to obtain design procedure for GSC design. The obtained design results and their properties are illustrated in the simultaneously design of controllers for nonlinear turbogenerator model (6-order). The results of the obtained design procedure are a PI automatic gain scheduled voltage regulator (AVR) for synchronous generator, and a PI governor gain scheduled controller.
