Abstract
A method for generating manipulated variables for the direct-axis and cross voltage, respectively, to represent the flux-forming current ID and torque-forming current IQ in field-oriented control of asynchronous machines, taking into account the stator voltage drop and steady-state internal voltage. The steady-state internal voltage is calculated on the basis of reference variables of the currents.
