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 ...

Comparison of a nonlinear adaptive controller with certainty-equivalence type adaptive controllers
(IEEE, 1995)Recently a new class of adaptive controllers for linear time invariant minimum phase plants has been proposed and analyzed. The design of these controllers is based on nonlinear tools and appears to be different from that ...

A comparison of classical, neural and fuzzy control schemes for the position control of an underwater vehicle
(2006)A comparative study for the automatic control of an underwater vehicle has been conducted. The vessel was equipped with only three thrusters (one on top, a second at port and a third at starboard) for the control of its ...
