Designing and evaluating control systems of the Dez main canal

Abstract: In the present study, a distant downstream proportional integral (PI) feedback control with decouplers and a local upstream PI feedback control were applied to the West main canal of the Dez irrigation system in Iran. The model of the proposed canal was formulated in the SOBEK simulation package. The control system was programmed in MATLAB. To evaluate the control system potential, simulations were done for two months of the real offtake schedule. The performance criteria of the maximum absolute error (MAE), t… Show more

“…This study considers the first 27 km of the west main canal, corresponding to 7 pools. The maximum discharge capacity at the head gate is 157 m 3 s -1 [17]. Figure 1 shows the profile of a longer section of the canal, composed by the first 13 reaches.…”

“…There are 71 turnout structures and 15 cross-structures such as inverted siphons, culverts and check siphons in the main canal. Figure 2 shows the longitudinal view of the test case and the details of geometric and structural information are available in (Isapoor et al 2011). The two characteristics of the ID model, delay time and storage area, are calculated by applying system identification technique at average flow conditions Isapoor et al 2011).…”

“…A model of the Dez Main Canal in Iran has been developed using all exact dimensions of the cross sections and gates of the canal. The model, whose profile can be seen in Figure 2, has been calibrated and used in multiple studies [10], [12], [54]. The simulations run with a time step of 30 s, which is accurate enough to capture all relevant low-frequency behavior and the resonances that may occur.…”
