Abstract

Provides a method for the parametric stabilization of nonlinear systems. Unlike traditional techniques, our approach does not assume that the equilibrium remains fixed for all parameter values. The proposed method is based on linear matrix inequalities, which are used to produce a robust control that accounts for uncertain parametric variations, and the corresponding equilibrium shifts. This strategy is successfully applied to the design of decentralized turbine/governor control in electric power systems with fluctuating load levels.
