چکیده انگلیسی
Software compensation is an effective method for enhancing the magnetic field environment adaptability of light-small fiber-optic gyroscope (FOG). In order to decrease the magnetic drift of FOG, an accurate magnetic sensor is typically required to measure the intensity of magnetic field in this software compensation method. The magnetic sensor generally suffers from the measurement error due to the variety of temperature. In order to compensate the magnetic drift of FOG preferably in full temperature range (−40 °C to +60 °C), the temperature sensitivity of the Hall sensor manufactured by Allegro is studied in this paper. Temperature compensation models of quescent voltage output and magnetic sensitivity are established, and the variation is compensated respectively. The measurement precision of Hall sensor is 0.02 G over the temperature from −40 °C to 60 °C after compensation, which meets the requirement of magnetic drift compensation of FOG in full temperature.
