Abstract
A device for controlling an electromechanical actuator includes an electric motor and an actuator operated by the electric motor. It also includes a digital signal processor (DSP) providing data of reference voltages (Ud, Uq) on the basis of an decoupled electrical model of the motor. The processor has at least one Park transformation module receiving measurement data for the currents of at least two supply phases of the motor (i_mot, i_mot) and a datum for the estimated angle of the motor (θ) and transforming them into data regarding the component of current with stator current axis (id) and the component of current in quadrature with the stator current (iq).
