摘　　要：针对现有输水工程中闸泵站控制模型测试体系不完善的问题展开探索,旨在进一步提升渠道输水控制模型在不同工况下的准确性和稳定性,以确保输水工程现场的安全与高效运行。将引黄济青工程明渠段作为研究区,将渠道输水控制系统中的控制模型作为测试对象,并基于LabVIEW(laboratory virtual instrument engineering workbench)开发系统组态,以水动力模型作为环境仿真模型,搭建模型在环(model-in-the-loop,MIL)测试系统,实现了闭环测试,验证所开发模型在环仿真系统和模型开发阶段对模型进行测试的可行性。本研究为渠道输水工程领域内的控制模型开发与测试工作提供关键的技术支撑,为提升输水工程的运行效率及增强其安全性奠定了坚实的基础。Addressing the uneven distribution of water resources and improving water ecological degradation,longdistance water transfer and cross-basin diversion through canal systems are effective approaches.The level of automation control of flow structures during water transfer directly impacts the efficiency of water distribution.With the rapid development of automation technology and continuous innovation in canal water transfer engineering techniques,canal water transfer control algorithms have been increasingly applied in practical water transfer projects.However,despite the expanding scope and depth of their application,a comprehensive and systematic development and test system for canal water transfer control algorithms has not yet been established,which affects the reliability of the algorithms to a certain degree.Various canal water transfer control algorithms that have not been fully developed and rigorously tested may not guarantee sufficient accuracy and stability when applied in the field under various working conditions.A hydrodynamic numerical simulation model and a canal water transfer simulation controller were established based on the current status of the research area.A model-in-the-loop(MIL)test system was designed and developed for the canal water transfer control system.This MIL test system provides technical support for improving the accuracy of canal water transfer control algorithms,reducing development costs,and achieving fine management of water distribution.Firstly,a one-dimensional hydrodynamic numerical simulation model was established.By discretizing the SaintVenant equations using the Preissmann four-point implicit difference scheme,the unsteady flow conditions in the canal were described.Meanwhile,the internal boundaries such as sluice gates and water outlets were generalized into corresponding control equations using the mass conservation equation and flow-discharge relationships,coupled with the discretized Saint-Venant equations to establish a one-dimensional hydrodynamic numerical sim
