Abstract: This article investigates the finite-time attitude tracking control problem of spacecraft with angular velocity sensor failures and actuator saturation. A model-free angular velocity ...

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional ...

Abstract: This article presents the design of a safe learning attitude controller, based on the Koopman operator (KO), for rest-to-rest spacecraft attitude ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Vikki Velasquez is a researcher and writer ...

I've been working on angular velocity estimation of an object from noisy pose measurements, which is a common problem in augmented reality and surgical applications. To test my algorithms, I needed to ...

Generating ground truth 6DoF pose, velocity, and acceleration data is crucial to verify many algorithms in robotics. This repository implements [1] with some modification to estimate translational and ...
