Event-triggered adaptive sliding mode control of cyber-physical systems under false data injection attack

• The event-triggered adaptive sliding mode control problem for cyper-physical systems under the false data injection attack is investigated. • By the combination of ASMC method and the event-triggered mechanism, an event-triggered ASMC scheme is developed to deal with the security control problem of CPSs subject to FDIA. • The formed design method can achieve the goal of system stability without knowing the upper bound information of the FDIA mode, and it can also reduce the event-triggered times and save the bandwidth resources effectively. This paper studies the event-triggered adaptive sliding mode control(ASMC) problem for the cyber-physical systems (CPSs) under the false data injection attack (FDIA). First, for the unknown upper bound information of the false data injection attack, the adaptive technique is used to estimate the upper bound of the attack mode. Then the event-triggered ASMC method is developed by combining with the event-triggered mechanism. Second, Lyapunov’s stability theory is used to prove the admissibility of the formed event-triggered ASMC design scheme. Finally, simulation results verifies the effectiveness and superiority of the proposed method, which ensures the security and stability of the system and improve the utilization of information resource.
