Event-driven Finite-Time Control for Continuous-time Networked Switched Systems under Cyber Attacks

Abstract This paper addresses the issue of event-driven state-feedback controller design for networked switched systems in the finite-time sense. At the plant design level, the synchronism between switched systems and the corresponding controllers is guaranteed by introducing a mode-decision unit at the actuator side. Through intensive time interval analysis approach, the switched system, the event-triggered scheme, transmission delays and cyber attacks are unified into a new closed control system. Sufficient conditions are developed to ensure the networked switched system finite-time bounded by constructing a proper Lyapunov function. Then, the design methods for switched sub-controllers, optimal event-triggered parameters and restrictive average dwell-time switching law are presented. It is worth pointing out that the main results not only contribute to optimize limited network resources but also improve the system security level, which is validated through an illustrative example of a boost converter circuit.
