An LMI Approach to Guaranteed Cost Control of Nonlinear Uncertain Large-Scale Systems with Time Delays

Abstract

The guaranteed cost control problem of the decentralized robust control for nonlinear large-scale systems with both norm-bounded time-varying parameter uncertainties and time delays is considered. Sufficient condition for the existence of guaranteed cost controllers is given in terms of the linear matrix inequality (LMI). It is shown that the decentralized local state feedback controllers can be obtained by solving the LMI.
