Abstract

The optimization in the configuration of network communication with time delays among field devices is a major challenging task of a networked control system (NCS). In view with the network-based model of literature, the present paper introduces the dynamic network scheduler to customize the aperiodic time delay for optimal bandwidth allocation of the network. This is achieved with the following three objectives: (a) classification of data packets among periodic and aperiodic communication using support vectors; (b) deciding the bandwidth associated with the priority weightage for aperiodic data packets; (c) simulation for fairness of NCS with dynamic network scheduler switching integrated the weighted fair queuing algorithm. The outcome of proposed dynamic network scheduler is compared with the network model of literature for reduced and bounded delays of aperiodic communication in NCS.

网络化控制系统中定制非周期通信的动态网络调度器

摘要

现场设备之间具有时间延迟的网络通信配置的优化是网络控制系统 (NCS) 的一项重大挑战任务。针对文献中基于网络的模型，本文引入动态网络调度器来定制非周期时延，以实现网络的最优带宽分配。这是通过以下三个目标实现的： (a) 使用支持向量在周期性和非周期性通信中对数据包进行分类；(b) 决定与非周期性数据包的优先权重相关的带宽；(c) 具有动态网络调度器切换的 NCS 公平性模拟，集成了加权公平排队算法。
