Measurement and controlling magnetic field strength by using hall effect sensors with classical algorithm

Abstract

In the article a non-contact measurement and controlling a magnetic field on the basis of Hall effect is presented. The structure of a Hall effect sensor was discussed. An example of a simple magnetic field measuring device, which uses the presented sensors, and a model of a magnetic field controlling system with a Hall effect sensor was presented in the paper. A solution system presented in the paper is based on using a ruler of Hall effect sensors to measure a magnetic field induction. The proposed arrangement of the sensors allows to measure the position of a launch trolley of a BSL launcher which uses the phenomenon of magnetic levitation.
