Control of a class of nonlinear systems by decentralized control

Abstract

This correspondence considers the control of a system composed of several interconnected subsystems. Each subsystem is described by a canonical nonlinear state model, with the restriction that interaction between different subsystems is linear. Under very mild additional conditions a decentralized dither feedback control is constructed which will drive the system state to zero. The dither control method is shown to stabilize this system for all initial conditions.
