Abstract:
A method for generating control parameters from a response signal of a controlled system with a computer, the method which comprises:sampling an input signal and a response signal for generating a sampled input signal and a sampled response signal; smoothing the sampled input signal and the sampled response signal with the aid of a time-variant filter for generating a smoothed input signal and a smoothed response signal by smoothing at least one of the sampled input signal and the sampled response signal in accordance with the formula: {tilde over (x)}=Vxv=Vywhere y denotes a vector consisting of samples of the response signal, V a matrix for smoothing, v a vector of a smoothed impulse response, x a vector of the input signal, and {tilde over (x)} a vector of the smoothed input signal; generating in each case frequency characteristics from the smoothed input signal and the smoothed response signal; forming a difference between the frequency characteristics in a Bode diagram; and determining control parameters with the aid of the difference.
