Conclusions
In this paper, the periodic event-triggered control strategy for CPSs under DoS attacks is investigated. An H∞ observer is used to relax the assumption of full-state information available and restrict the influence of the disturbance and noise. A predictor is designed to predict the system state in the interval between any two continuous eventtriggering. Besides, the lower bounded of the inter-event times is obtained to exclude continuous triggering of each verification period. In this way, the transmission interval is extended, and the communication resources are saved. Input-to-state stability analysis is proposed when sufficient condition on the duration and frequency of the DoS attacks is satisfied, and using the upper bound of the prediction error, the conservativeness of the tolerable of DoS attacks is reduced. Finally, a simple numerical simulation and a batch reactor system simulation have been given to illustrate the effectiveness of the proposed control strategy.
