Device for controlling an electromechanical actuator

Device for controlling an electromechanical actuator comprising an electric motor and an actuator operated by the electric motor, characterized in that it comprises a digital signal processor (DSP) providing data of reference voltages (Ud—ffw, Uq—ffw) on the basis of an decoupled electrical model of the motor, the processor comprising at least one Park transformation module receiving measurement data for the currents of at least two supply phases of the motor (i_mot_2, i_mot_3) and a datum for the estimated angle of the motor (θestimated) 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—ref), a module for comparing these data with reference values of current with stator current axis (id—ref) and of current in quadrature with the stator current (iq_ref) providing, through integral proportional correctors (IP) data for the voltage variation (del_Ud, del_Uq), the voltage variation data being combined with the reference voltage data (Ud—ffw, Uq—ffw) at the input of a vector regulation module operating an inverter for supplying the motor with pulses of modulated width.
