摘要: 针对网络控制系统中随机时延的建模问题,在对网络时延产生原因和构成进行分析的基础上,通过搭建网络时延采集平台获得真实网络系统的随机时延数据,根据试验结果建立了网络时延数学模型.该模型能够更加准确地描述网络时延的特征,可用于网络时延预测和高性能时延补偿控制研究.Abstract: Aiming at the problem of the modelling of stochastic time delay in network control system (NCS),a time delay dynamic model was put forward based on the experimental data by analyzing the cause and construction of the time delay in NCS and constructing an experimental platform to acquire the real time stochastic delay data.The proposed model could describe the characteristics of the network time delay more accurately and be used in time delay prediction and high performance time-delay compensation controller design of NCS.
