CLASSIFICATION OF CANAL CONTROL ALGORITHMS

Different control algorithms for the regulation of irrigation canals h ave been developed and applied throughout the world. Each of them can be characterized according to several criteria, among which are: the c onsidered variables (controlled, measured, and control action variable s), the logic of control (type and direction), and the design techniqu e. This paper defines these terms and classifies the algorithms detail ed in the literature. To summarize and compare algorithms, a structure d table of the main published canal control algorithms is presented.
