| Abstract: | In this paper, the canal control algorithms in the automatic systems ofirrigation districts have been summarized. The control algorithms were classifiedinto three types which are considered variables, logic of control and designtechniques. The advantages and disadvantages of each algorithm were analyzed andcompared. A developing trend is predicted that is more comprehensive control systems,including dominating control of down stream level, combining feedback and feedforwardcontrol, using modern control theories such as artificial neural network, fuzzycontrol, system identification and generic typology etc. and unsteady simulationmodels as well. New control algorithms will widely be applied in multi-usage andmulti-objectives of irrigation districts. |
