Title (EN) SYSTEMS AND METHODS FOR CORRECTING NON-SINUSOIDAL SIGNALS GENERATED FROM HIGH SPEED INDUCTIVE SENSORS
(FR) SYSTÈMES ET PROCÉDÉS DE CORRECTION DE SIGNAUX NON SINUSOÏDAUX GÉNÉRÉS À PARTIR DE CAPTEURS INDUCTIFS À GRANDE VITESSE
Abstract:
(EN) A high speed sensor system including coupler, a sensor, a memory module, and a processor module is provided. The sensor includes a transmitter coil adapted to be energized by a high frequency current source and at least two receiving coils. One of the receiver coils generates a sine-like function output signal and the other generates a cosine-like function output signal upon rotation of the coupler. The memory module is operable to compensate for non- sinusoidal output signals caused by the high speed sensor system and the gap between the coupler and the at least two receiving coils. The processor module is communicatively coupled to the memory module. The processor module is configured to process the non-sinusoidal output signals from both the first and second receiver coils, determine the offset error, and generate a corrected output signal representative of the rotational position of the coupler.
(FR) L'invention concerne un système de capteur à grande vitesse comprenant un coupleur, un capteur, un module de mémoire et un module de processeur. Le capteur comprend une bobine émettrice conçue pour être excitée par une source de courant à haute fréquence et au moins deux bobines réceptrices. L'une des bobines réceptrices génère un signal de sortie de fonction de type sinus et l'autre génère un signal de sortie de fonction de type cosinus lors de la rotation du coupleur. Le module de mémoire peut être utilisé pour compenser des signaux de sortie non sinusoïdaux dus au système de capteur à grande vitesse et à l'entrefer entre le coupleur et lesdites au moins deux bobines réceptrices. Le module de processeur est couplé en communication au module de mémoire. Le module de processeur est configuré pour traiter les signaux de sortie non sinusoïdaux en provenance des première et seconde bobines réceptrices, déterminer l'erreur de décalage et générer un signal de sortie corrigé représentatif de la position de rotation du coupleur.
