Modélisation et analyse du chariot mobile du radiotélescope de Nançay

The goal of this study is to model the moving of the mobile cart of the Radiotelescope of Nancay in order to be able, to set up a method of diagnosis. The principle of this method is to transform the equations of the model so as to obtain called particular relations ARR: Analytical Redundancy Relations which bind only known variables. They make it possible to detect and locate the faults thanks to the table of signatures of the faults. Simulations illustrate this method.
