摘　　要：简要介绍了积分-时滞模型及其参数率定过程,对积分-时滞模型进行离散化处理构造出全状态空间模型,利用状态空间模型对扰动可预知算法进行设计。最后,将该算法应用在美国亚利桑那州Maricopa Stanfield灌溉输水区W-M支渠,并和当前使用的线性二次型(LQR)算法进行比较和分析,得出一些应用性结论,这些结论对于渠道运行控制系统设计及算法选择均具参考价值。This paper briefly introduces an integrator-delay model and its parameter calibration.A complete state and space model that was constructed by time discretization of the continuous integrator-delay model was adopted to design a foreseeable algorithm for optimized scheduling.This algorithm was evaluated through application to the W-M lateral canal in the Maricopa Stanfield irrigation and drainage district in central Arizona,U.S.A.and it was compared with the commonly-used LQR algorithm.Application experiences and in-depth analysis were obtained.These results are useful for design of operation control system and selection of algorithms.
