Title (EN) CONTROLLER FOR AN ELECTROMECHANICAL TRANSDUCER
(FR) DISPOSITIF DE COMMANDE DE TRANSDUCTEUR ÉLECTROMÉCANIQUE
Abstract:
(EN) A controller for an electromechanical transducer is provided. The controller comprises driving means operable to actuate a mechanical output of the transducer; impedance cancelling means operable to at least partially cancel an electrical impedance of the transducer; and linearising means between an input of the controller and the driving means. The linearising means are operable to generate an output signal by modifying an input signal of the linearising means to compensate for nonlinear behaviour of the transducer. The linearising means are operable to receive one or more state signals indicative of one or more state variables of the transducer, the one or more state signals comprising a velocity signal indicative of a velocity of the mechanical output of the transducer.
(FR) L'invention concerne un dispositif de commande d'un transducteur électromécanique. Le dispositif de commande comprend : des moyens d'entraînement permettant d'actionner une sortie mécanique du transducteur ; des moyens d'annulation d'impédance permettant d'annuler au moins partiellement une impédance électrique du transducteur ; et des moyens de linéarisation entre une entrée du dispositif de commande et les moyens d'entraînement. Les moyens de linéarisation peuvent générer un signal de sortie par la modification d'un signal d'entrée du moyen de linéarisation afin de compenser le comportement non linéaire du transducteur. Les moyens de linéarisation peuvent recevoir un ou plusieurs signaux d'état indiquant une ou plusieurs variables d'état du transducteur, le ou les signaux d'état comprenant un signal de vitesse indicatif d'une vitesse de la sortie mécanique du transducteur.
