Frequency domain, parametric estimation of the evolution of the time-varying dynamics of periodically time-varying systems from noisy inputoutput observations
Frozen and instantaneous transfer function determine the speed of time-variations. The equivalence of different LTP models is performed at the level of the HTFs. Consistent estimators are derived for LTP systems from noisy inputoutput data. Successful demonstration of the identification scheme on real measurements.
