Instrumentation électronique reconfigurable : modélisation et validation expérimentale d'un système de mesure auto-étalonnable

Abstract : This thesis subject relates to define and design a standard calibration system in order to correct a measurement chain and ensure the desired accuracy. The adopted solution will allow auto-test and auto-adjustment routines, in order to ensure its availability during its calibration, reduce the relative cost and guarantee the required measurement accuracy. This solution consists in designing a reconfigurable instrumentation based on the use of a field programmable analog array chip (FPAA). The measurement chain transfer curve is periodically corrected by using the polynomial progressive calibration method, ensuring a systematic correction of each taken measurement. An experimental test bench was carried out and different sensor types have been studied. The obtained results highlight the simplicity of implementation and the efficiency of the proposed calibration method and shows well how the measurement accuracy can be considerably improved.
