Unified non-fragile controller design for event-triggered networked control systems

摘要

This paper focuses on the problem of unified non-fragile controller design for networked control system with an event-triggered scheme. The main objective of this paper is to design the H_∞, L₂ -L_∞, passivity and (Q, S, R)-dissipativity in a unified framework so as to guarantee that the network control systems is asymptotically stable and extended dissipative. The extended dissipativity performance analysis unifies (Q, S, R)-dissipativity, H_∞, passivity, and L₂ - L_∞ performance in one unified framework by regulating some weight matrices. By using Lyapunov stability theory and multi-delay partitioning method, some delay-dependent criteria in terms of linear matrix inequality(LMIs) are proposed. In addition, a non-fragile state feedback controller are designed to ensure that the closed-loop system satisfies the extended dissipative performance. Finally, a numerical example is given to illustrate the efficiency of the addressed method.
