Abstract

The generation of robust periodic excitation signals to measure and identify the frequency response function of (linear) dynamic systems is studied. Such signals should result in a maximal signal-to-noise ratio in a given measurement time, have a low sensitivity to nonlinear distortions, while at the same time they should be user friendly and robust to misuse by inexperienced users. Random phase multisines are proposed that meet all these requirements: in one experiment not only the frequency response function is measured, also the disturbing noise levels at input and output are determined, and the nonlinear distortions of the plant are characterized.
