摘要
针对EPC物联网络系统中存在的随机性时延,剖析了EPC物联网络系统的结构及特点,并建立了EPC物联网络系统的控制模型,其中时滞满足Markov链要求。研究了EPC物联网络控制系统的H∞随机控制问题,基于LMI方法,可以很方便地求出状态反馈控制器,并可使闭环系统具有良好的动、静态性能和抗干扰能力。
This paper is concerned with a stochastic H∞ control problem for a class of EPC Internet of things with transmission delays, where the delays are time -varying and different in every transmitted process,thus the delays can be described by a Markov chain. Based on the LMI approach,a new method for designing a memoryless static state feedback control law is proposed to stabilize,the closed loop system and to reduce the effect of the disturbance input on the controlled output to a prescribed level for all admissible transmission delays. The results depend on the solvability of a certain linear matrix inequality and may be less conservative.
