Liénard type model of fluid flow in pipelines: Application to estimation
Résumé
This paper highlights how fluid flow in a pipelinecan be represented as a nonlinear model of so-called Liénardtype. It is then shown how the structure of this model is suitablefor the design of algorithms to identify parameters of a pipelineor estimate unmeasurable states. This approach is illustratedby simulation results, for instance showing how to estimate theDarcy-Weisbach friction coefficient or the fluid acceleration.
