中文摘要：
针对带宽受限的多回路网络控制系统提出一种模糊反馈调度方法。首先利用二次型函数映射的动态权重调整策略对控制回路赋予不同的权重系数，继而考虑控制系统输出的误差和误差变化率，提出了改进的基于模糊反馈调度的优先级配置策略，设计了模糊反馈调度器，对各控制回路的优先级进行动态的调整。最后通过TrueTime工具箱建立了动态权重调整的多回路网络控制系统的模糊反馈调度仿真模型，并将该方法同EDF（earliestdeadlinefirst）与权重固定的模糊反馈调度方法进行对比。仿真结果表明在相同的网络带宽占用的情况下，该方法具有更小的网络时延，且具有较好的性能。
英文摘要：
For a multi-loop resource constrained networked control system, a fuzzy dynamical scheduling method is presented. First different weight coefficients of the control loop was given through a quadratic function mapping dynamic weight adjustment strategy. Then considering the change of output and error rate in the system, an improved fuzzy feedback priority scheduling strategy was proposed and a fuzzy feed- back scheduler was designed; the priority of each control loop was adjusted dynamically. Finally, Tru- eTime toolbox was used to model the networked control system wifich contains dynamic weight adjustment fuzzy feedback scheduling, and it was compared with earliest deadline first（EDF） and fixed weight fuzzy feedback scheduling method. The simulation results show that the method in the paper provides a smaller time-delay and better control performance under the same network bandwidth usage.
