1. Introduction1. IntroductionThe aim of this project was to control the
filling of each pond of the Scipio Open Channel in the right time, minimizing the water loss at the end of the canal.
The most difficult was that only a positive action was available on the system.
Many controllers were tested in this project to find the best one.

2. System Specification2. System Specification
Sensors and actuators can be used just one time each hour.
Gate height, Diversion water level and Pond water Level are available for each Pond.
Gate height, Water level and Outflow are available for the Reservoir.

Diversion Flow CalculationDiversion Flow Calculation
For each diversion gate, the flow was calculated using the derivative of the pond volume variations.
Thus, the points related to the gate height, the diversion pond height and the flow were plotted.
Seeing these plots, so many points had very low flows for many values of gate heights and diversion pond heights. That is why a Look-up Table, based on 5 values of diversion pond heights and 5 values of gate heights, was made for the model.
So for each cell of the Look-up Table, the average was taken in the neighborhood of the point.

Time Delay CalculationTime Delay Calculation
To Calculate the Time Delay between the reservoir and each diversion, the Rootcanal software was used: http://www.neng.usu.edu/bie/faculty/merkley/BIE6300.htm
Through Google Earth the topographic datas of the Scipio channel were obtained to model it on this software (elevations, distances)
Thus, 3 Look-Up Tables were made to calculate the delay relative to the Reservoir outflow for each part of the canal.
So each part of the canal was represented by a delay : y (t)= u (t-τ)

Delay ModelingDelay ModelingFor each part of the canal, Delays were modeled like this :
But for parts between diversions and Ponds, Delays were modeled by constant delays.
Johnnie’s Pond Delay=0.2 hours, Tom’s Pond Delay=0.2 hoursCity’s Pond Delay=0.1 hours and Cemetary’s Pond Delay=0.5 hours

6. Conclusion6. Conclusion
The efficiency, for this system, of the PIIα
controller compared to others controllers was shown in this study.
Also an other strategy based on cooperative control could be applied but this one is hard to control due to the system complexity.
