Optimal control of unstable water movement in channels of irrigation systems under conditions of discontinuity of water delivery to consumers

Abstract

The object of research was the site of the South Golodnostepsky main channel, located in the north-east of the Republic of Uzbekistan. Scientific and research work is being carried out in the world aimed at improving and developing methods, quality criteria, developing mathematical models and algorithms for solving problems of optimal control of the operating modes of water facility using modern information systems. We used methods of mathematical modeling and optimal control of systems with distributed parameters, which is considered the main channel. The optimum changes in water levels at times and along the length of the section of the main channel are obtained, and its open gates allow increasing the water level along the length of the section. During t = 20.7 minutes the water level at the end of the main channel section rises by 1.8 meters.
