Abstract

For nonlinear controlled optical storage drives, a frequency-domain measurement approach is shown to be effective in demonstrating both stability and performance. In an experimental setting based on an industrial optical playback (CD drive) device, the motivation for applying such an approach is illuminated. It is shown that performance can efficiently be assessed using a describing function approach on a model level and using swept-sine measurements on an experimental level. The validity and effectiveness of the approach is extensively shown via closed-loop measurements.
