Abstract

This paper proposes an output feedback controller for nonlinear networked control systems (NCSs). Based on Lyapunov Krasovskii functional, the sufficient condition of stability is derived in terms of LMI(Linear Matrix Inequality) when controller gain is given. Moreover, the output feedback controller is designed by using free weighting matrices. The derived sufficient condition is less conservative than ones shown in the literature. Numerical examples are given to show that the condition is less conservative of the proposed methods.
