摘　　要：针对水闸群闭环控制难以稳定运行问题,基于信息融合技术,通过引入明渠水动力学关系、并在系统输入变量上叠加"误差流量",实现分散且孤立的实时监测数据之间的关联,使闸群水流系统具有必要的信息冗余,以实现水闸群的水情信息融合,进而进行动态预测。并基于水位、流量等水情预测信息,通过增加水闸调节输入信息的途径,提出一种改进水闸群调节的方法。通过模拟试验测试并验证了该方法对改进PID调节具有较好的效果。It is difficult to run stably and smoothly in a closed control system of floodgates.So,a control method was proposed based on information fusion.Using the hydrodynamic of open ditches,fitting the deviation flow into the input part of system and building the correlation among isolated systems,so as to get redundant information and enhance the fusion of water flow of floodgates,then monitoring them dynamically.By the forecast information of water flow and the input information of floodgate adjust,a method of improved the floodgate adjust sets was given.The simulation experiment verified the good result of improved PID adjustment sets.
