| Popis: | Water is the most important element of food production, and the easiest and most cost-efficient way to transport it is through open-channel irrigation systems (OCIS). These types of systems have a high agricultural and ecological impact. However, in most countries, OCIS lack automation and efficiency at mitigating the economic and environmental costs that the waste of water is causing. In order to identify modeling strategies and the best control practices, this paper presents an overview of the main factors of control-oriented models and control strategies for OCIS. In modeling, two fields are considered: (i) models that come from simplifications of the Saint-Venant Equations (SVE); and (ii) approximate models. For each category, a brief description of the control-oriented modeling strategies is given. In the control field, five relevant aspects are considered: (i) centralized, decentralized, and distributed architectures; (ii) control objectives; (iii) regulation structures and control-action variables; (iv) feedback and feedforward configurations; and (v) control strategies. For each aspect, the most important features are explained. Finally, with the aim of establishing the acceptability of the reported modeling and control techniques, as well as challenges that remain open, a discussion and a case study are presented. |
