Abstract

The security control approach is presented for cyber-physical systems (CPSs) with missing measurements and cyber-attacks based on an improved dynamic event-triggered scheme (DETS). The DETS is proposed to decrease the communication workload and reduce the effects of mutation data which may be erroneous. The sensor measurements are assumed to be lost randomly due to the unreliable network. In this paper, an observer-based controller is derived which can be tolerant towards the impacts of the missing measurements and cyber-attacks. The observer-based controller parameters and event-triggered parameter are co-designed. Finally, simulation results verify the validity of the proposed approach.
