Abstract

A study of the friction model for the leak detection with a nonlinear observer is presented. Classically the friction model in leak detection algorithms only relies on a constant parameter. In the present work, the use of a more elaborate friction model is considered, with a coefficient explicitly depending on the flow, either algebraically, or even differentially. Those friction formulations are implemented within a nonlinear-observer-based algorithm for detection and location of leaks, which is analyzed, and tested with real measurements on some experimental pipeline prototype. Some conclusions and recommendations about this extended friction modeling are finally given.
