چکیده
The fluxgate magnetometer has the advantages of having a small volume and low power consumption being light weight is commonly used to detect weak magnetic targets, including ferrous metals, unexploded bombs (UXOs), underground corrosion pipelines. However, detection accuracy affected by its own error. To obtain more accurate data, sensor must be error-corrected before application. Previous researchers easily fell into local minimum when solving error parameters. In this paper, correction method was proposed tackle problem, which combines Dragonfly algorithm (DA) Levenberg–Marquardt (LM) algorithm, thereby problem LM improving Firstly, we analyzed sources three-axis established model. Then, parameters were solved using DA–LM respectively. addition, comparing results two methods, found that accurate. Finally, measurement data corrected. simulation show can accurately solve triaxial sensor, proving effectiveness algorithm. experimental difference between corrected ideal total value decreased from 300 nT 5 nT, further verified

A Miniature Magnetic-Force-Based Three-Axis AC Magnetic Sensor with Piezoelectric/Vibrational Energy-Harvesting Functions
In this paper, we demonstrate a miniature magnetic-force-based, three-axis, AC magnetic sensor with piezoelectric/vibrational energy-harvesting functions. For magnetic sensing, the sensor employs a magnetic-mechanical-piezoelectric configuration (which uses magnetic force and torque, a compact, single, mechanical mechanism, and the piezoelectric effect) to convert x-axis and y-axis in-plane and...
متن کاملThree-axis Satellite Attitude Control Based on Magnetic Torquing
Magnetic torquing is attractive for generation of control torques on small satellites. The concept is that interaction between the Earth's magnetic eld and a magnetic eld generated by a set of coils in the satellite is used for actuation. This principle is inherently nonlinear, and diicult to use because control torques can only be generated perpendicular to the geomagnetic eld vector. So far, ...
