In the present study, two robustcontrol systems of the Local Upstream PI Feedback Control with Filters and Centralized DistantDownstream PI Feedback Control with Filters and Decouplers were designed and applied for the westmain canal of Dez irrigation network. The control algorithms programmed in MATLAB m-files andconnected to the SOBEK Canal Flow module through the SOBEK Real Time Control module. Toevaluate the efficiency of the control algorithms, the performance criteria of the Maximum AbsoluteError, Integral Absolute Error and Steady State Error were considered during the simulations of onemonth with regard to the real off takes schedule with the highest variations within the cropping season.The results indicated that the applied control algorithms have considerable potential to closely matchthe discharge at the downstream check structures with those ordered by water users while maintainingthe water level throughout the length of the canal. It was also concluded that the centralized controlsystem has more efficiency compared to local control system which provides flexible, demandoriented and accurate operation procedure. Considering that local upstream controller may beconsidered as an option, either as the main control system or as the backup system for the canal systemautomation.}, keywords = {}, title_fa = {ارزیابی عملکرد دو الگوریتم کنترل در بهبود فرایند بهره برداری از کانال اصلی غرب شبکه آبیاری دز}, abstract_fa = {}, keywords_fa = {}, url = {https://jhyd.iha.ir/article_85519.html}, eprint = {https://jhyd.iha.ir/article_85519_5238740f234d46657fc4a53558cb89b8.pdf} }
