1. A method for operating a mechatronic system with a power converter, comprising:
providing a pulse width modulation signal with a variable switching frequency by a hysteresis-based pulse width modulator;
influencing a hysteresis limit by a controller
as a function of an actual value of an instantaneous switching frequency and
as a function of a harmonic frequency of the mechatronic system.
