Open water channels are used to distribute irrigation water to farms and they are large scale systems consisting of many interacting subsystems. The operational objective is a trade-off between a high level of service to farmers and a good water delivery efficiency, and it is well known that automatic control systems can help in achieving these objectives. However in practice, controllers may not...
The problem of satisfying constraints imposed on a dynamical system that operates under a load schedule is considered from the perspective of using model predictive control to set free inputs across time. We formulate an approach incorporating information about the schedule and identify conditions for when it is guaranteed to work. The proposed method is motivated and simulated within the context...
One key problem for canal system control is how to select appropriate performance indicators and how to tune the controller with these indicators. A canal system is a multi-input and multi-output (MIMO) system. The judging control performance can be extremely complicated. In this paper, frequently used canal system performance indicators are evaluated. Then these indicators are used individually to...
Open-channels networks used for water distribution are subject to algal developments that can induce major disturbances such as clogging issues on hydraulic devices (pipes, weirs, filters,...). We already studied the use of flushes to manage these algae developments. The flush is carried out by increasing the hydraulic shear conditions using the hydraulic structures of the canal network. In response...
The main canal of the middle route of South-to-North Water Transfer Project crosses four drainage areas and eight latitudes from south to north, almost across half of China in a north-south direction, and most part of the main canal is in the north of the Yellow River. Different degree of Ice freezing will occur from the north to the south in winter, and may cause disasters such as ice jamming and...
