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

This article focuses on the stability analysis for a nonlinear networked control system (NCS) and develops the asynchronous quantizer-dependent event-triggered control mechanisms considering the limitation on plant-to-controller and controller-to-plant channels. First, the observer-based controller, coder, decoder, and asynchronous quantizer-dependent event-triggered control mechanisms are proposed based on system characteristics, and nonlinear NCSs are reformulated to overcome the shortage of system states. Second, the nonlinear NCS with no delay is considered, and sufficient conditions are proposed to guarantee stability and avoid Zeno behavior. Moreover, the nonlinear NCS with input delay is further discussed, and the 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.
