Adaptive decentralized control for a class of nonlinear systems

摘要

The problems of nonlinear complex system control design are still in the centre of attention and there exists no universal solution by now. The aim of this paper is to propose the control algorithm for nonlinear systems consisting of several subsystems. The subsystem nonlinearities are assumed to be known and the state variables are accessible only locally. The interactions between subsystems can be unknown, but bounded. The proposed control algorithm for such class of complex systems is based on the feedback linearization technique with automatic adjusting of the subsystem decay rate. The control performances are illustrated by an example of nonlinear system consisting of two interconnected subsystems.
