Landmark-Based Drift Compensation Algorithm for Inertial Pedestrian Navigation

open access: yesSensors, 2017
The navigation of pedestrians based on inertial sensors, i.e., accelerometers and gyroscopes, has experienced a great growth over the last years. However, the noise of medium- and low-cost sensors causes a high error in the orientation estimation ...

A Correction Approach for the Inclined Array of Hydrophones in Synthetic Aperture Sonar

open access: yesSensors, 2018
A correction approach for the inclined array of hydrophones is proposed to prevent decline of the image quality in SAS. In this approach, the 2-way exact acoustic propagation path of the inclined array is transformed into the sum of a single root term ...

An output feedback tracking controller for ships with nonlinear damping terms [PDF]

open access: yesModeling, Identification and Control, 1996
A tracking controller with wave filter for ships with nonlinear manoeuvring characteristics is derived. Only measurement of the yaw angle is needed to assure global asymptotic stability of the yaw angle and yaw rate of the ship about the desired yaw ...

Structural Characteristics of Wind Turbines with Different Blade Materials Under Yaw Condition

open access: yesEnergies
The uneven distribution of airflow on the blade surface of a yaw wind turbine triggers a complex non-constant flow, resulting in turbine flow field operation disorder, which, in turn, affects the structural field.

LSTM-NN Yaw Control of Wind Turbines Based on Upstream Wind Information

open access: yesEnergies, 2020
Based on wind lidar, a novel yaw control scheme was designed that utilizes forecast wind information. The new scheme can reduce the power loss caused by the lag of accurate measurement data in the traditional yaw control strategy.

Further Study on the Effects of Wind Turbine Yaw Operation for Aiding Active Wake Management

open access: yesApplied Sciences, 2020
Active wake management (AWM) via yaw control has been discussed in recent years as a potential way to improve the power production of a wind farm. In such a technique, the wind turbines will be required to work frequently at misaligned yaw angles in ...
