Periodic event-triggered dynamic output feedback control for networked control systems subject to packet dropouts.

This paper proposes a co-design method of dynamic output feedback control law and periodic event-triggered control (PETC) strategy to tolerate a maximum allowable number of successive packet dropouts (MANSDs) in networked control systems (NCSs). For the purpose of striking a balance between saving limited communication resources and reducing complexity of the transmission implementation, we present the periodic event-triggering mechanism (PETM), in which the triggering conditions only needs to be monitored at each event-verifying instant. In NCSs, packets often suffer from some interference in network transmission, such as packet losses. For packet dropouts, we introduce a dropout variable and model the whole closed-loop systems as a hybrid system. Furthermore, some stability conditions for co-design are given by a novel Lyapunov function and stability theorems of hybrid systems, and the explicit designs parameters of controller and triggering conditions are presented to ensure L 2 stability. Finally, two illustrated examples are given to show the effectiveness of the proposed design methods. • A co-design method of PETM and control law is proposed to save network resource. • The method aims at achieving desired stability properties while tolerating a MANSD. • The method provides less conservation results than the emulation-based approach. • The overall system is modeled based on the hybrid system framework. • By using a modified Young's inequality, rigorous stability analysis is provided.
