H∞ output quantized control for networked control systems under resilient event-triggered mechanism and aperiodic denial-of-service attacks

This paper studies H-infinity output quantized control for networked control systems (NCSs) under resilient event-triggered mechanism (ETM) and aperiodic denial-of-service (DoS) attacks. First, by integrating attack information into triggering conditions, an output-based resilient ETM is introduced. Second, a switched system model is established, which integrates impacts of aperiodic jammer, resilient ETM, quantization, and disturbances into a unified framework. Third, less conservative exponential stability criteria are obtained with guaranteed H-infinity performance. Further, sufficient conditions for co-designing dynamic output feedback controller and resilient ETM are presented. Finally, an example confirms effectiveness of the proposed methods.
