摘要: Abstract Fixed algae developments induce strong constraints for the management of open-channel networks. They cause clogging issues on hydraulic devices and can sometimes lead to water quality alteration. An original strategy limit algal biomass is carry out regular flushes. A flush performed by increasing shear conditions using structures canal. Consequently stress increase, a part fixed detached, then re-suspended into column, finally transported canal network. This leads peak turbidity that needs be controlled. The present paper proposes quasi-linear model response discharge used automatic controller design. parameters are identified real calibration based continuous monitoring turbidity. Flushes simulated whole branch an intermediate reach in order test ability simulate propagation peak. Then, develop open-loop efficiency will depend its amplitude duration. design objective consists maximizing detachment without exceeding maximal level, as little possible. designed tested nonlinear model.
