Youla parameterized adaptive vibration suppression with adaptive notch filter for unknown multiple narrow band disturbances

Abstract

The vibration caused by the multiple narrow band disturbances exists widely in the mechanical systems. In this paper, a Youla parameterized adaptive control approach is introduced for the rejection of unknown multiple narrow band disturbances. The adaptive notch filter weighted Q (Youla) parameter is adopted to the online internal model principle-based regulator, so that the disturbances can be fully attenuated and the robustness of the closed-loop system is improved. A central controller is first designed to obtain the desired baseline loop shape. Then, the controller is augmented by a notch filter weighted Q parameter to construct a series of stable controllers and the Q parameter in the stable controllers is tuned online to obtain the desired controller. The adaptive control method is applied in a data storage system to attenuate the flying height vibration and the experimental results illustrate the effectiveness of the proposed approach in rejecting unknown multiple narrow band disturbances.

Advances in Youla-Kucera parametrization: A Review

“…The use of YK parametrization Q in adaptive noise and vibration rejection context covered different applications requiring high control precision and low noise sensitivity as: wafer scanning in semiconductors Chen, Jiang, and Tomizuka (2015) , data storage systems (reading/writing) Chen and Tomizuka (2013) ; Martinez and Alma (2012) ; Wu, Zhang, Chen, and Wang (2018) , mechatronics Tomizuka (2008) , active suspension systems Doumiati et al (2017) ; Landau, Constantinescu, and Rey (2005) , and biochemistry Valentinotti et al (2003) where the regulation problem is to maximize the biomass productivity in the fed-batch fermentation of a specie of yeasts and the cell growth is considered as an unstable disturbance rejected by the YK parameter Q. In Luca, Rodriguez-Ayerbe, and Dumur (2011) the feedback YK noise rejection controller is extended to control a LPV plant.…”
