Construction and Evaluation of PID Control System for Irrigation Canals in Laboratory Scale %R 10.30482/jhyd.2011.85456 %X Automation is one of the main options for improving operations and increasing flexibility inirrigation canals. Construction and testing of related technology is one of initial and mainattempts in reaching this goal.. In this research PID classical control system was constructed,and tested at a laboratory flume. The hardware of the system includes the depth and gateopening sensors, motor, slide gate, electronic boards and computer. The software part of thesystem is the PID control system, which is developed and connected with equipments usingLABVIEW software. To study the performance of the constructed control system, differentscenarios of sudden changes of upstream and downstream flow were tested. Maximum AbsoluteError (MAE), Integral of Absolute magnitude of Error (IAE) and System Response Time (SRT)indicators are used for evaluating the performance of the system. The results showed that theperformance of the developed upstream and downstream control system is appropriate,However, downstream PID control system showed better performance when compared to theupstream PID control system. The developed PID automatic control system and experiencesgained from constructed facilities could be implemented in irrigation canals. %U https://jhyd.iha.ir/article_85456_24edf47e1ae2c9c6748c918ffbc7e78d.pdf
