Abstract
A method for operating a polyphase machine having a pulse-width-modulated inverter includes: determining a setpoint current value respectively for a current in the longitudinal direction and/or the transverse direction based on a specified torque, ascertaining a setpoint voltage value respectively for a voltage in the longitudinal direction and/or the transverse direction with the aid of the setpoint current value and/or of an actual current value determined at the pulse-width-modulated inverter, controlling and/or regulating the polyphase machine corresponding to the ascertained setpoint voltage value. In this context it is provided that, in addition, using a model, a model value is determined respectively for the voltage in the longitudinal direction and/or the transverse direction, the difference between the setpoint voltage value and the model value is ascertained, and in response to the exceeding of a specifiable maximum difference, an error signal is triggered.
