Abstract: Magnetic encoders are widely used in motor drive systems. The existence of harmonic greatly reduces the accuracy of angle demodulation. Based on the angle tracking algorithm of the dual ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...

ABSTRACT: Geomagnetic storms significantly disturb the ionosphere, impacting satellite-based systems such as the Global Navigation Satellite System (GNSS), communication links, and power ...

Abstract: The vernier absolute magnetic encoder generates the sine signals from a master magnetic and a nonius magnetic track and they are processed to infer the absolute angle information. However, ...
