According to the invention, estimated values (id (EST), iq (EST)) of the motor currents of a synchronous machine are determined by an observer in a co-ordinate system that rotates together with a rotor, independently of the target values (ud, uq) of electric voltages of the synchronous machine (PMSM) in the co-ordinate system that rotates with the rotor. |
