ℋ∞ output tracking control for network-based control systems

This paper focuses on ℋ_∞ output tracking control for network-based control systems with the physical plant in continuous time and the controller in discrete time. The main contribution of the paper is that a new form of the augmented closed-loop system is proposed, which can improve control performance. Based on a Lyapunov-Krasovskii functional and a LMI (linear matrix inequality)-based procedure, a state feedback controller which contains network-induced delays and data packet dropouts is designed for a class of linear systems. Finally, simulation results show that the proposed scheme is superior to some existing schemes in the literature.
