Observer-Based Feedback Control for Networked Control Systems With Quantisation and Packet Dropouts

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 135)


The paper investigates Networked Control Systems (NCSs) with quantisation and packet dropouts both the sensor-to-controller (S/C) and controller-to-actuator (C/A). Firstly, the signals both the S/C and C/A are quantised using a logarithmic quantiser while the packet dropouts are modeled as two Bernoulli distributed white sequences. Then, an augmented model is proposed based on an observer, and a sufficient condition is derived for NCSs to be the exponentially mean-square stable. Finally, simulation results confirm the effectiveness of the proposed method.
