Abstract

La présente invention concerne un dispositif de commande de la vitesse d'un moteur par limitation de courant L'invention concerne un dispositif du type comportant des moyens pour générer un premier signal représentatif de la vitesse instantanée du moteur, des moyens pour générer un second signal représentatif d'une vitesse désirée du moteur, des moyens pour agir sur lesdits premier et second signaux, en vue de générer un troisième signal représentatif de la différence entre les vitesses instantanée et désirée du moteur, et des moyens sensibles au troisième signal, en vue de fournir un signal de commande du moteur, ce signal de commande étant en relation connue avec le troisième signal, ledit dispositif étant caractérisé en ce qu'il comporte : des moyens de blocage 50 destinés à empêcher que le troisième signal dépasse une valeur maximale variable, fonction du premier signal. Application à la commande de la vitesse d'un moteur.The present invention relates to a device for controlling the speed of a motor by current limitation The invention relates to a device of the type comprising means for generating a first signal representative of the instantaneous speed of the motor, means for generating a second signal representative of a desired engine speed, means for acting on said first and second signals, in order to generate a third signal representative of the difference between the instantaneous and desired engine speeds, and means responsive to the third signal, in order to provide a motor control signal, this control signal being in a known relationship with the third signal, said device being characterized in that it comprises: blocking means 50 intended to prevent the third signal from exceeding a variable maximum value , depending on the first signal. Application to the control of the speed of an engine.
