Asynchronous Quantizer-Dependent Event-Triggered Control for Nonlinear Networked Control System With Observer-Based Controller

摘要

This paper focuses on stability analysis for nonlinear networked control system and develops the asynchronous quantizer-dependent event-triggered control mechanisms considering the limitation on plant-to-controller and controller-to-plant channels. Firstly, the observer-based controller, coder, decoder and asynchronous quantizer-dependent event-triggered control mechanisms are proposed based on system characteristics, and nonlinear networked control systems are reformulated to overcome the shortage of system states. Secondly, the nonlinear networked control system with no delay is considered, and sufficient conditions are proposed to guarantee stability and avoid Zeno behavior. Moreover, the nonlinear networked control system with input delay is further discussed, and Lyapunov-Krasovskii function is constructed. Finally, the robotic manipulator system is selected as the example to verify the feasibility and superiority of our proposed scheme.
