Tecnica de control de nivel de agua no lineal para un sistema de canales abiertos de dos tramas

International audienceThis paper is related to water level nonlinear control design in two-reach open channel flow systems. Open channel flow is known to be described by non linear partial differential equations (Saint Venant equations). A finite dimensional model has been previously developed by orthogonal collocation weighted residual method. This model was used for control by input-output linearization technique for one open channel reach. For two reaches, control gates make the connection between them and at the same time make the control implementation more difficult, since only three gates will be available for two reaches, while two gates were previously considered for every single reach. Here it is proposed to solve this problem by using a weight balancing technique for common control gate. With this technique it becomes possible to use the control developped for a single reach to cases with two or more reaches. The implemented simulations show very satisfactory results
