摘　　要：提出一种基于发布/订阅中间件结构的物联网环境下语义感知前馈反馈控制设计方法。面向大规模物联网,包含许多发布者,它们从物理世界和逻辑传感器收集实时数据,进行实时数据分发算法设计,利用了两个控制环来实现预期的Qo S和Qo D,通过双环路控制,得到语义感知前馈反馈控制改进设计模型。仿真实验表明,该语义感知前馈反馈控制,降低了通信开销,提高了语义感知的控制性能。通过本文设计带控制器的物联网语义感知,始终将CPU负载控制在目标值附近,相反不使用控制器时,CPU波动严重,设计的控制方式为负载变化不可预测的物联网提供了较好的自适应能力。Proposed a semantic aware publish / subscribe middleware structure of feedforward IOT environment under feedback control design method based on. For large scale Internet of things, contains a number of publishers, they collect realtime data from the physical world and the logical sensor, algorithm design of real time data distribution, using the two control loop to achieve the desired Qo S and Qo D, through the double loop control, feedforward feedback control to get semantic perception improved design model. Simulation results show that the semantic aware feedforward feedback control, reduces communication overhead and improves the control performance of semantic perception. IOT semantic aware through this design with controller, and always will be the CPU load to near control values in the target, the opposite does not use CPU controller, severe fluctuations provides good adaptive ability for load control mode design of unpredictable changes in the Internet of things.
