Improved Dynamic Event-Triggered Control for Nonlinear Systems with Fading Channels

This paper is devoted to the protocol-based control design for nonlinear systems with fading channels. Distinguished from the existing event-triggering criteria associated with only two consecutive packets, an improved dynamic event-triggered protocol is formu-lated, which accounts for some historical available transmitted packets. As a consequence, the number of triggering times can be reduced efficiently while maintaining desired con-trol performance. Meanwhile, the time-varying fading channel is described by a Markov process within finite space, whose mode can be detected via a hidden Markov mode de-tector. Based on Lyapunov stability theory, sufficient conditions are derived to achieve the stochastic stability of the closed-loop system. In the end, the validity of the derived results is verified through an application study.(c) 2023 Elsevier Inc. All rights reserved.

Automated summary

This paper focuses on the design of protocol-based control for nonlinear systems with fading channels. It proposes an improved dynamic event-triggered protocol that considers historical transmitted packets to efficiently reduce triggering times while maintaining desired control performance. The time-varying fading channel is modeled as a Markov process, and a hidden Markov mode detector is used to detect the mode. Sufficient conditions are derived based on Lyapunov stability theory to achieve stochastic stability of the closed-loop system. The validity of the results is verified through an application study.
