A Fast Algebraic Estimator for System Parameter Estimation and Online Controller Tuning—A Nanopositioning Application
IEEE Transactions on Industrial Electronics(2019)
摘要
Parameter uncertainty is a key challenge in the real-time control of nanopositioners employed in scanning probe microscopy. Changes in the sample to be scanned introduces changes in system resonances, requiring instantaneous online tuning of controller parameters to ensure stable, optimal scanning performance. This paper presents a method based on the frequency-domain algebraic derivative approach...
