Adaptive disturbance rejection for disk drives using neural networks
(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 LQ control with anti-windup augmentation to optimize UAV performance in autonomous soaring applications
(2008)The performance of a glider can be considerably improved by means of soaring and optimization of its trajectory. Recent advances in the area of static soaring assume known linear glider dynamics and no actuator saturation ...

Adaptive mode-suppression and disturbance-rejection scheme with application to disk drives
(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 ...

Article
Adaptive notch filter using real-time parameter estimation
(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 ...

A neural-networks-based adaptive disturbance rejection method and its application to the control of hard disk drives
(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 ...

Practical robust adaptive control: Benchmark example
(2008)A novel disturbance rejection solution for a benchmark mass-spring-damper (MSD) system is presented. The proposed design, adaptive mixing control (AMC,) is a deterministic multiple model adaptive control (MMAC) approach ...

Robustness and Performance of Adaptive Suppression of Unknown Periodic Disturbances
(2015)In recent years, a class of adaptive schemes has been developed for suppressing periodic disturbance signals with unknown frequencies, phases, and amplitudes. The stability and robustness of these schemes with respect to ...

Stochastic uncertain systems subject to relative entropy constraints: Induced norms and monotonicity properties of minimax games
(2007)Entropy and relative entropy are fundamental concepts on which information theory is founded on, and in general, telecommunication systems design. On the other hand, dissipation inequalities, minimax strategies, and induced ...

Time-varying optimal disturbance minimization in presence of plant uncertainty
(2009)The optimal robust disturbance rejection problem plays an important role in feedback control theory. Here, its time-varying version is solved explicit ly in terms of duality and operator theory. In particular, the optimum ...
