Robust Nonlinear Position Control with Extended State Observer for Single-Rod Electro-Hydrostatic Actuator

open access: yesMathematics, 2021
In the existing literature, studies on position controller design using only position feedback, considering the disturbances for single-rod electro-hydrostatic actuators (EHAs), have not been reported.

Atomic position localization via dual measurement [PDF]

open access: yes, 2001
We study localization of atomic position when a three-level atom interacts with a quantized standing-wave field in the Ramsey interferometer setup.

Measuring position and momentum together [PDF]

open access: yesPhysics Letters A, 2008
We describe an operational scheme for determining both the position and momentum distributions in a large class of quantum states, together with an experimental implementation.

Trajectory Planning for Navigation Aiding of Autonomous Underwater Vehicles

open access: yesIEEE Access, 2020
Autonomous underwater vehicles can perform seabed surveys with a higher resolution and quality than from equivalent ship-mounted sensors. Although high-grade inertial navigation systems aided by Doppler velocity logs can operate without external position

Standard Quantum Limits for broadband position measurement [PDF]

open access: yes, 1998
I utilize the Caves-Milburn model for continuous position measurements to formulate a broadband version of the Standard Quantum Limit (SQL) for monitoring the position of a free mass, and illustrate the use of Kalman filtering to recover the SQL for ...

Steffensen's inequality for positive measures [PDF]

open access: yesMathematical Inequalities & Applications, 2015
We generalize Steffensen’s inequality for positive measures. We obtain conditions for these inequalities which are invariant in form to Steffensen’s inequality for absolutely continuous measures. Further, we produce linear functionals which generate exponential convexity and Cauchy means.

ULES: Underwater Localization Evaluation Scheme Under Beacon Node Drift Scenes

open access: yesIEEE Access, 2018
In underwater sensor localization scenes, beacon nodes (BNs) with known coordinates are deployed to localize unknown nodes (UNs). However, the BNs are likely to drift due to undercurrents, geological changes, and marine biological activities, which will ...

New methods and functionalities for railway maintenance through a draisine prototype based on RADAR sensors

open access: yesIET Intelligent Transport Systems, 2023
Inspection of the railway tracks requires relying on a precise positioning system that accurately determines the location of potential failures and deficiencies. Therefore, measuring the speed and precise location of rail vehicles is essential.

Measurement of a quantum particle position at two distant locations: a model

open access: yesActa Polytechnica, 2022
A simplified one-dimensional model of measurement of the position of a quantum particle by two distant detectors is considered. Detectors are modelled by quantum particles bounded in potential wells with just two bound states, prepared in the excited ...
