Hysteresis Quantizer-Based Event-Triggered Control of Nonlinear Networked Control Systems

In this paper, we present a novel event-triggered control mechanism for nonlinear systems with hysteresis quantization. To describe the tendency of the dynamic quantizer parameter, an auxiliary parameter is created and the relationship between the quantizer parameter and the auxiliary parameter has been discussed. Via thoroughly analyzing the structure of the hysteresis quantizer, the hysteresis quantizer based event-triggered control mechanism is designed to appropriately decide the accurate signal transmission instants with simple calculation process. Moreover, under the proposed method, the nonlinear system could be stabilized and Zeno behavior could be intrinsically avoided. Furthermore, a numerical example is given to demonstrate the efficiency of the proposed mechanism.
