英文摘要：

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.
