Abstract

The paper presents the theoretical model and implementation of the magnetoelectric ring sensor. The designed device is capable of measuring the constant magnetic field of low amplitudes (even several dozen nT). To determine its capabilities and resolution, the hysteresis characteristics were evaluated and measured. Besides the theoretical description of the sensor, two heuristic approaches were used to approximate the internal characteristics (including the hysteresis loop), solving the regression task: a multilayered perceptron and support vector machine. Experiments show that the former has minimally Mean Square Error, which suggests its better applicability for heuristic modeling of the real-world device.
