Observer-Based H-infinity Controller for Nonlinear Singular Networked Control Systems

Abstract

Based on observer, for a class of nonlinear continuous singular networked control systems, considering the time-varying network-induced delay, a new controller and observer co-designing technique are developed with H-infinity performance norm, a sufficient condition for the existence of the investigated controller is derived, and a systematic design approach is addressed by using Lyapunov-Krasovskii function and linear matrix inequalities (LMIs) for the controller designing. Finally, an example is provided to demonstrate the validity of the proposed method.
