Abstract

This paper is concerned with the secure state estimation and event-triggered control problem for continuous-time cyber-physical systems (CPSs) under actuator and sensor attacks. Based on output measurements, an intermediate estimator is constructed to estimate the state and the malicious attacks simultaneously. Furthermore, a compensating controller is designed based on the intermediate estimator via the event-triggered communication. It is proved that the state of the estimation error system and the closed-loop system are both uniformly ultimately bounded. Simulation examples verify the effectiveness of the proposed method.
