摘要

This paper discusses the stability of a nonlinear networked control system with limited channels under denial-of-service (DoS) attacks. The transmitted signals in both plant-to-controller and controller-to-plant channels are asynchronous, and each channel is under the threat of DoS attacks. To overcome the negative effects raised by imperfect channels and DoS attacks, the relationship among encoder structure, DoS attacks and triggering characteristics is thoroughly analyzed and the asynchronous encoder-based event-triggered control mechanisms are novelly proposed. Moreover, both encoding and decoding schemes are designed to ensure the transmission efficiency. Furthermore, the QSR-dissipativity, finite-gain L 2 stability and input-feedforward output-feedback passivity of the nonlinear system are analyzed. Finally, experiments are conducted to illustrate the validity and superiority of the proposed scheme.
