Supervised internal multi-model control of a dam-gallery open-channel system

In this paper, a method for designing a supervised internal multi-model controller (SIMMC) is proposed. The structure is well-adapted for regulating non-linear plants for which some operating modes can be represented. A multimodeling method making possible to represent the operating modes is proposed. The supervision of the operating mode is carried out online and is combined with a control accommodation method which switches to the best controller. The considered plant is a dam-gallery open-channel system supplying a river with water and permitting all downstream uses. The effectiveness and the performances of the SIMMC are shown on a simulation of the plant using the real geometrical and physical data.
