A Robust L2-Lx Filter Design for Networked Control System with Logarithmic Quantization

摘要：

In this paper, a robust L2-Lx filter for networked control system is designed. A continuous model of networked control system is investigated and it is denoted by the one that is similar to time-delay system, through some assumption and transformation. Because the signal must be quantized before it is transported in the network, time-invariant logarithmic quantization is considered in the output of system. The filtering error system designed in this paper is robustly asymptotically stable and fulfils the given L2-Lx performance level. Based on a linear matrix inequality approach, a solving method of the filter is provided. A numerical example is given to show the effectiveness of the method.
