A method for automated startup and/or for automated operation of controllers of an electrical drive system with vibrational mechanics with the following steps: (a) determining a preliminary value of at least one parameter; (b) determining a model of the electrical drive system by determination of initially a non-parameterized model through the recording of frequency data during operation of the drive system subject to the utilization of the preliminary value of at least one parameter and the subsequent determination of parameters of the electrical drive system based on the frequency data and subject to optimization of at least one preliminary value of at least one parameter by a numerical optimization method on the basis of the Levenberg-Marquardt algorithm and (c) parameterizing at least one controller of the electrical drive system by at least one of the determined parameters.
