Resilient adaptive event-triggered dissipative control for networked control systems with DoS attacks

Abstract

This paper focuses the design of resilient control for networked control systems with an adaptive event-triggered mechanism in the presence of denial-of-service attacks, actuator saturation and actuator faults. The model for denial-of-service attacks (DoS-As) in networked control systems, which mainly destroy the control channel and occur aperiodically with an unknown attack strategy, is constructed. An adaptive event-triggered mechanism (AETM) is introduced to reduce unimportant communication transmissions in a network provided adaptive varying threshold while maintaining satisfactory system performance. By using the Lyapunov function approach, linear matrix inequality (LMI)-based sufficient conditions are obtained to ensure the exponential stability and satisfying the prescribed performance index of the closed-loop systems under DoS-As. Moreover, the feasibility of the jointly developed schemes for the control gain and event-triggered parameters is calculated using the presented LMIs. The potentiality of the proposed scheme is validated using a numerical example.
