H∞ controller design for continuous networked control systems based on a switched system approach

Abstract

In this paper, the H∞ controller design problem is investigated for continuous networked control systems (NCSs). Based on a switched system approach, we establish a novel NCSs model, by which the proposed H∞ controller changes along with the system modes. By using Lyapunov stability theory and Wirtinger-based integral inequality, sufficient conditions for the mean square stability and stabilization of the continuous networked control systems are achieved. Finally, two simulation examples are exploited to demonstrate the correctness and effectiveness of the presented controller design method.
