Abstract: International audience ; This article presents a methodology for a fasterdevelopment of observers. On board real-time high frequencymeasurements are logged and used as inputs to validate anopen-loop observer in an offline simulation. It allows embeddedimplementation constraints to be taken into accountas early as possible in the development process. The proposedmethod facilitates and speeds up the design procedurecompared to on-board validation, which often involves trialand error gain tuning. The suggested approach is illustratedthrough the design of an observer for mechanical sensorlesscontrol of Permanant Magnet Synchronous Moteur (PMSM)using an industrial benchmark. The solution is implementedon a low-cost microcontroller, using Rapid Control Prototyping(RCP) on Matlab/Simulink. The overall strategy andlogged data are available online under an open-source license.
