摘要/Abstract

摘要： 研究了一类具有IEEE802.11b无线网络通道特性和时变特性的离散系统镇定及数值仿真问题。分别建立了刻画IEEE802.11b无线网络通道时滞的逆高斯分布模型和系统时变特性的不确定参数模型。设计了基于模型的状态反馈控制器以补偿网络延时和时变性对系统的影响。同时分析了离散时变网络控制系统的随机稳定性,并给出了线性矩阵不等式形式的控制器求解条件。通过数值仿真分析,验证了所提方法的有效性。

关键词: 网络控制系统, 时变系统, 逆高斯分布模型, 基于模型的控制

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
