摘要
针对EPC物联网络系统中存在的时变与不确定性时延问题,建立了EPC物联网络系统的控制模型,假设系统中的时延满足一定的结构性要求下,研究了EPC物联网络控制系统的H∞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。数值算例及仿真结果证明了所得结论的有效性。
The time varying and uncertain delays are inevitably existed in the EPC Internet of things, The control model is set up for the EPC Internet of things, Based on this model, the H∞ control problems are studied in terms of LMI methods. It is very convenient to obtain the state feedback controller such that the closed loop system has very good dynamic and static performance. Simulation results proved the effectiveness of our result.
