Open-channel flow model approximation for controller design. (English) Zbl 0835.76011
Summary: Open-channel flow is analyzed using the linearized St.-Venant equations. A method is presented to derive an approximation model for an open channel with backwater effects; the approximation model consists of functions that allow the application of the effective control synthesis methods. The accuracy of the approximation models is demonstrated by two examples.
