Observers with unknown inputs for Estimation of the Road Profile
Résumé
This paper deals with a new method for estimation of the road profile using partial measurements of vehicle dynamics. This method is based on a robust observer designed with a nominal dynamic model of the vehicle. This model is a linear half-car model whose inputs have been considered as unknown states to be estimated. The estimation accuracy of our observer has been validated experimentally using a trailer equipped with position sensors and accelerometers.
