Analysis and Simulation of a Class of Time-varying Wireless Networked Control Systems

Abstract

Abstract: The problem of stabilization was investigated for a class of discrete time-varying systems over a physical IEEE 802.11b wireless channel. The wireless network-induced delays were characterized by an inverse Gaussian distribution model (IGDM) and the time-varying nature was depicted by uncertain parameter model. The model-based state feedback controller was designed to compensate the influence of delays and time-varying nature. And the stochastic stabilisability of discrete time-varying networked control system was analyzed and the solution of controller was given in the form of linear matrix inequalities (LMIs). The effectiveness of the proposed methods was illustrated by numerical simulation examples.

Key words: networked control system, time-varying system, inverse gaussian distribution model, model-based control
