For the attitude stabilization, we propose a nonlinear finite-time observer using quaternion-based attitude representation.
Then, to improve the performance and precision of the attitude estimation at high frequencies, we propose to add gyroscope and to develop an approach relaying on a quaternion-based nonlinear filter for the tracking of rigid body attitude (orientation) and heading.
Then, considering model uncertainties and unknown external disturbances, we propose a robust adaptive attitude synchronization controller by designing adaptive laws to estimate the unknown parameters.
Based on the previous findings, we proposed the following hypothesis: Attitude towards purchasing green sportswear positively relates to a consumer's purchase intention for green sportswear.
Look at these out-of-touch paranoiacs, accusing us of being fascists, if you can credit it, when all we did was talk in fascist language, encourage fascist attitudes and propose fascist solutions.
Fitting attitude (FA) theories propose to analyze value, or some limited range of values, in terms of evaluative attitudes endorsed as fitting or, alternatively, as appropriate, correct, merited, proper, rational, or warranted.
The semantics of representational attitude verbs they propose is given in 7, and I take the verb believe for illustration here.
The problem of Earth pointing attitude control for a spacecraft with magnetic actuators is addressed and a complete architecture combining algorithms for detumbling, attitude acquisition and nominal attitude regulation is proposed.
But 50 years ago last month, a letter to the magazine Nature ended the passive, look-up-and-ponder attitude by proposing a scientific, experimental approach.
In this paper, an analytical attitude is proposed for solving linear systems by Homotopy Analysis Method (HAM).
