Abstract

Background and Objectives: Due to water resources shortage in our country, improvement of water distribution management is unavoidable matter for increase irrigation network performance. Control systems have an important role in water distribution irrigation network and network successful depends on performance. Successful modeling and running depends on tuning of control coefficients. Aim of this study is determination of optimal control coefficients using SCE method.Materials and Methods: In this study, PID controller (upstream control and downstream control) is developed for slide gate on the ICSS MODEL. For tuning coefficients, SCE algorithm is used for increment and decrement operation scenario in MC CANAL OF ALBORZ IRRIGATION NETWORK with 12.6 km length at 5 hr time operation. The objective function consists of three performance indexes of MAE (Maximum Absolute Error), IAE (Integral of Absolute Error) and dimensionless form of SRT (System Response Time). Also Molden and gates indexes is used for performance assessment canal.Results: Optimal coefficients controller are gained in operation scenario. Using gained coefficients, model will be able to tune water level in target level in increment and decrement process at short time. Maximum errors are related to C1 structure with 10 cm in upstream controller and C3 structure with 6 cm in downstream controller. Upstream controller are not able to tuning water level in downstream, so water supply in TO14 and TO16 is disturbed and MPA index is fair and poor performance classes Respectively for TO14 and TO16. The MPA index have been improved in downstream controller Compared to upstream controller. MPA, MPF, MPD indexes are good performance classes in both controller and MPE index is fair.Conclusion: Results show gained optimal coefficients of the developed model to the upstream and downstream controllers is Responsive to changes in operation in a short time.
