Event-Triggered Security Defense Control for Remote Motor Under DoS Attack

In this article, an event-triggered sliding mode predictive control method for remote motor systems under Denial of service (DoS) attacks is investigated. First, an adaptive reaching law with integral sliding mode strategy is designed. The stability of the designed sliding mode strategy is demonstrated. Second, a security control generator based on sliding mode predictive control is proposed, which releases predictive control sequence to reduce the impact of sensor signal interruption caused by DoS attacks on system stability, and its stability is proved. Further, an event-triggered mechanism with better-dynamic performance is proposed by introducing dynamic loss factor. Finally, the effectiveness of the designed method is demonstrated by a simulation experiment and a semi-physical simulation together.
