Adaptive control of Networked Distributed Systems with unknown interconnections
(Institute of Electrical and Electronics Engineers Inc., 2016)Networked Distributed Control Systems (NDCS) consist of a number of interacting subsystems and usually face the challenge of delays induced by the communication network. In this paper we consider the case where each subsystem ...

Adaptive control of time‐varying plants: Simple examples
(1988)The design and properties of an adaptive model reference scheme and an adaptive pole placement control scheme for linear time‐varying plants are demonstrated via two simple examples. The two new schemes combine new control ...

Adaptive control of unmanned aerial vehicles in atmospheric flight with reduced models
(2007)We propose an approximate implementation scheme for an adaptive linear quadratic control structure by employing a balanced truncation procedure in the loop prior to solving the associated Algebraic Riccati Equation (ARE). ...

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 scheme for an aeroelastic airbreathing hypersonic cruise vehicle
(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 ...

Article
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 ...

Adaptive quadratic functional estimation of a weighted density by model selection
(2010)We consider the problem of estimating the integral of the square of a probability density function f on the basis of a random sample from a weighted distribution. Specifically, using model selection via a penalized criterion, ...
