摘　　要：针对无线传感器网络节能输出控制过程中,受到网络系统时滞性的影响,导致节能控制输出与期望输出之间存在较大控制误差的问题,提出利用事件驱动离散时不变系统研究无线传感器网络节能输出反馈控制机制。根据无线传感器系统的组成结构,针对反馈关联大系统进行建模,通过对系统的时滞项进行状态约束,并结合模糊控制调节规则构造网络节能输出反馈控制函数,以此为基础,通过设计驱动条件和时不变系统的状态空间模型,完成网络节能输出反馈控制机制的研究。仿真对比实验结果表明,所提控制机制的控制输出与期望输出之间的控制相对误差更小,节能效果较好。Aiming at the problem of large control errors between the energy-saving control output and the expected output due to the influence of network system time delays during the energy-saving output control process of wireless sensor networks,an event driven discrete time invariant system is proposed to study the energy-saving output feedback control mechanism of wireless sensor networks.According to the composition structure of wireless sensor system,the feedback related large-scale system is modeled,and the network energy saving output feedback control function is constructed by state constraining the time-delay term of the system and combining fuzzy control regulation rules.Based on this,by setting the event type and discrete system model reasonably,the network energy saving output control is realized.The contrast experiment proves that the relative error of the designed control method is small,and the energy-saving effect is better.
