Abstract
A method for controlling a multiphase voltage signal in a closed-loop manner is provided. The multiphase voltage signal is supplied to at least one phase set of a stator of an electric machine of a drive system of a motor vehicle for the purpose of generating a torque-specific, rotary magnetic field. The method includes determining a fundamental space vector representing a fundamental of the voltage signal, determining at least one harmonic space vector representing a harmonic of the voltage signal, adding the fundamental space vector and the at least one harmonic space vector to form a summed space vector, determining whether the summed space vector exceeds a predetermined threshold value, and limiting the summed space vector in such a manner that the limited summed space vector falls short of the threshold value.
