H驴 Controller Design of State Feedback Networked Control Systems with Long Delay and Packet Dropout

摘要

This paper studies the problem of designing robust H驴 controllers for state feedback networked control systems (NCSs) with long time delay and packet dropout. A switched delay-based method is proposed to model the NCSs with long time delay and packet dropout as switched systems, then the H驴 controllers are designed for the obtained switched systems by using LMI-based method. The H驴 controller design using the proposed switched delay-based method is proved to be less conservative than the controller design using the existing parameter uncertainty-based method. The simulation results illustrate the effectiveness of the proposed H驴 controller design methods.
