Event-triggered quantized-data feedback control for linear systems

Abstract

This paper proposes an event-triggered quantized-data feedback control scheme for linear systems. An event-triggered communication scheme is introduced to select which sampled-data should be quantized and transmitted to the controller. The threshold is constructed by considering the difference between the current sampled data and the latest quantized data. A finite-level dynamical quantizer is developed based on the communication scheme and quantized data. An output feedback controller is designed to ensure that the state of the closed-loop is uniform ultimate bounded. A numerical example illustrates the effectiveness of the proposed approach
