中文摘要：

控制算法是明渠运行自动化控制系统的核心。多年来各国学者开发出大量的明渠控制算法,对最近10余年的研究成果进行了综述。从技术特点、国内外研究进展、应用现状和存在的问题几个方面,对PID类算法、最优控制算法、模型预测控制算法和鲁棒控制算法作了重点评述,对它们的发展方向进行了展望。在评述国内该领域研究现状的同时,还从研究内容、仿真手段、试验条件几方面阐述了与国外的差距,提出了努力的方向。

英文摘要：

Control algorithm is the key part of canal control system.Different canal control algorithms have been developed during the past decades.Progresses in research on these algorithms in the last ten years are reviewed.Four typical canal control algorithms,i.e.PID control algorithm,optimal control algorithm,model predictive control algorithm and robust control algorithm are discussed in detail.The feature,application,development,and problem existed of these algorithms are commented.Proposals on the development direction of them are put forward.The gap between domestic and foreign researches is discussed from the aspects of content,simulation condition and physical model test condition,and some suggestions are given.
