摘要：AbstractWe present a method to identify the physical parameters of rotational systems with compliant load coupling in a robust manner. To ensure sufficient excitation, a pseudo random binary signal (PRBS) is automatically parameterized based on the noise level in the available feedback signal. To identify the plant parameters, we rely on a two step procedure: Firstly, the user is asked to mark distinct features in the non-parametric estimate of the frequency response. These features serve to calculate initial parameter guesses. Secondly, a non-convex curve fitting problem is solved to refine the parameter estimates. Experimental results verify that the method allows to robustly identify parameters even for small amounts of raw data resulting from short measurement times.
