For a method for controlling and regulating a synchronous machine which is operated from a converter and has indirect flux orientation, that is to say the flux position which is necessary for control is calculated from the rotor position and the reference variables for the currents, and the components of the actual value of the terminal voltage are additionally determined, the object exists of compensating for the errors in the rotor model during the calculation of the reference variables for the angle delta and during the calculation of the reference variable for the energy current iE, by means of a feedback. This is achieved in that the coordinates (um, ul) of an actual voltage value (u alpha , u.) with respect to the precalculated position of the flux are determined with the aid of a coordinate rotating element (3'), in that the error between the I component of the voltage vector and the reference value psi is supplied to a first flux regulator (11a) whose output signal corrects the parameter Lh in the rotor model, and in that the error between the m component of the voltage of the flux and the required value is supplied to a second flux regulator (11b) whose output signal is used for correction of the model parameter Lhq/Lhd. <IMAGE>
