Positive Real Synthesis of Networked Control System : An LMI Approach

Riyanto Bambang, Imam Arifin

Abstract


This paper presents the positive real analysis and synthesis for Networked Control Systems (NCS) in discrete-time. Based on the definition of passivity, the sufficient condition of NCS is given by stochastic Lyapunov functional. The controller via state feedback is designed to guarantee the stability of NCS and closed-loop positive realness. It is shown that a mode-dependent positive real controller exists if a set of coupled linear matrix inequalities has solutions. The controller can be then constructed in terms of the solutions.
