网络控制系统中基于上界时延的控制补偿
Control compensation based on upper bound delay in networked control systems
摘要：
近年来，人们对网络控制系统（NCS）的兴趣激发了通信网络和控制的研究。网络控制系统的分析通常是从网络或控制的角度进行的，但没有多少论文存在的分析都是在同一背景下进行的。本文对网络控制系统进行了全面的分析。首先，给出了在交换式以太网中获得分组传输的上界延迟值的过程。接下来，所获得的延迟估计用于延迟补偿，以提高控制系统的性能质量（QoP）。提出的上界延迟算法应用了网络微积分理论的思想。为了提高QoS，提出了基于Smith预估器的时延补偿策略和基于鲁棒控制的时延补偿策略，并进行了比较。
英文摘要：
Recent interest in networked control systems (NCS) has instigated research in both communication networks and control. Analysis of NCSs has usually been performed from either the network or the control point of view, but not many papers exist where the analysis of both is done in the same context. In this paper an overall analysis of the networked control system is presented. First, the procedure of obtaining the upper bound delay value for packet transmission in the switched Ethernet network is presented. Next, the obtained delay estimate is utilised in delay compensation for improving the Quality of Performance (QoP) of the control systems. The presented upper bound delay algorithm applies ideas from network calculus theory. For the improvement of QoP, two delay compensation strategies, the Smith predictor based and the robust control based delay compensation strategies, are presented and compared.
