Abstract

L'INVENTION CONCERNE UN PROCEDE ET DISPOSITIF D'ASSERVISSEMENT DE L'ORIENTATION D'HELIOSTATS, CHACUN MOBILE EN ROTATION AUTOUR DE DEUX AXES DE PIVOTEMENT. CE PROCEDE CONSISTE, POUR CHAQUE HELIOSTAT, A COMPARER LES TRAJETS, D'UNE PART, D'UN RAYONNEMENT REEMIS PAR LA CHAUDIERE EN DIRECTION DE L'HELIOSTAT CONSIDERE, D'AUTRE PART, D'UN RAYONNEMENT REFLECHI PAR L'HELIOSTAT VERS LA CHAUDIERE, ET A ASSERVIR LA ROTATION DUDIT HELIOSTAT AUTOUR DE SES AXES DE PIVOTEMENT POUR TENDRE A SUPERPOSER CES RAYONNEMENTS. L'INVENTION PERMET D'OBTENIR UN ASSERVISSEMENT EN BOUCLE FERMEE, SUPPRIMANT L'INFLUENCE DE PERTURBATIONS EXTERIEURES.
