Abstract

This paper studies the problem of designing robust H∞ controllers for networked control systems (NCSs) with both network-induced time delay and packet dropout by using active varying sampling period method, where the sampling period switches in a finite set. An active varying sampling period method using both clock-driven and event-driven sensor is proposed, then by modeling the system with varying sampling period as a switched system, H∞ controllers are designed by using LMI-based method. The simulation results illustrate the effectiveness of the active varying sampling period method and the proposed H∞ controller design.
