Claim One:
1. Method for automated startup or for automated operation of controllers of an electrical drive system with vibrational mechanics, the method comprising the following steps: a. determining a preliminary value of at least one parameter, b. determining a model of the electrical drive system by means of determination of initially a non-parameterized model through 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 the optimization of at least one preliminary value of at least one parameter by means of a numerical optimization method on the basis of Levenberg-Marquardt's algorithm and c. parameterizing at least one controller of the electrical drive system by means of at least one of the determined parameters; wherein a two-mass oscillating system is used as a model of the electrical drive system or the model of the electrical drive system is determined without a-priori knowledge of the electrical drive system; wherein as a preliminary value of a parameter a total startup time of the electrical drive system is estimated, from frequency response data in the range of small frequencies, and is used as the starting value for the numerical optimization method on the basis of the Levenberg-Marquardt algorithm; and wherein a preliminary value of the total startup time is estimated based on the quotient of the number of measured values of a partial signal sequence and the sum of the contributions of a general transfer function depending on angular frequencies from 1 to the number of measured values, to which the total startup time is proportional.
