SISTEMA DI CONTROLLO E PIL0TAGGIO DI UN ATTUATORE ELETTROMAGNETICO ASINGOLO AVVOLGIMENTO IMPIEGANTE UN UNICO AMPLIFICATORE OPERAZIONALE

摘要

A system for controlling and driving an electromagnetic actuator includes a unique operational amplifier in the regulation loop for driving the electromagnetic actuator and for monitoring, during different phases of operation, the current in the actuator and the back electromotive force. The new architecture allows for a considerable reduction of the area of integration of the system as a whole.
