Event‐Triggered Sliding Mode Adaptive Anti‐Disturbance Switching Control for Switched Networked Systems Under DoS Attacks

ABSTRACT An event‐triggered sliding mode adaptive anti‐disturbance switching control scheme is presented for switched networked systems (SNSs) subjected to multi‐source disturbances and DoS attacks. Firstly, a switching adaptive regulator is proposed to estimate unknown parameters of the switching neural network disturbance model. This adaptive regulator provides faster convergence and is applicable to the non‐switched system case as well. Then, a switching adaptive estimator is constructed to approximate the switching neural network disturbance. Additionally, a resilient event‐triggered mechanism (RETM) is applied, which not only mitigates the adverse effects of DoS attacks on communication but also facilitates the enhancement of communication resource utilization. Under the average dwell time (ADT) switching signals, the controller is built to reduce the effects of disturbances modeled by the neural network and alleviate the impact of unmodeled disturbances. At last, a switched RLC example is employed to display the efficacy of the proposed event‐triggered sliding mode adaptive anti‐disturbance switching control scheme.
