Adaptive disturbance rejection for disk drives using neural networks
Levin, J.; Pérez Arancibia, N. O.; Ioannou, Petros A.; Tsao, T. -C (2008)This paper presents the experimental verification of an adaptive feedforward disturbance rejection scheme for hard disk drives. The control scheme is shown to reduce the error during track-following by as much as 11.8%. ...

Adaptive mode suppression scheme for an aeroelastic airbreathing hypersonic cruise vehicle
Levin, J.; Ioannou, Petros A.; Mirmirani, M. D. (2008)This paper presents an adaptive mode suppression scheme that is simulated on a longitudinal model of a generic airbreathing hypersonic flight vehicle. An aerodynamically optimized vehicle model is used which has a long ...

Adaptive mode-suppression and disturbance-rejection scheme with application to disk drives
Levin, J.; Ioannou, Petros A. (2009)The goal of a track-following controller for a disk drive is to maintain as close to perfect tracking as possible. Better tracking allows for more data to be stored on a single disk. There are several factors which make ...

Adaptive notch filter using real-time parameter estimation
Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A. (2011)The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation ...

Multirate adaptive notch filter with an adaptive bandwidth controller for disk drives
Levin, J.; Ioannou, Petros A. (2008)This paper presents the simulation results performed of a multirate adaptive notch filter with adaptive bandwidth controller for disk drives. The resonant modes of a disk drive may be uncertain and vary between units, and ...

A neural-networks-based adaptive disturbance rejection method and its application to the control of hard disk drives
Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A.; Tsao, T. -C (2009)This paper presents a neural-networks-based disturbance rejection adaptive scheme for dealing with repeatable and nonrepeatable runout simultaneously. The effectiveness of this method is demonstrated empirically on a ...
