摘要
半球谐振陀螺仪受到温度影响产生漂移。针对半球谐振陀螺组合设计了一套基于脉宽调制的温控系统。通过对陀螺组合温控方式的选取、均匀对称性结构设计、热模型建模,利用FPGA对陀螺仪进行温控系统设计。实验表明,温控系统精度为±0.1℃,满足陀螺性能要求。
To decrease the temperature drift of the hemispherical resonant gyroscope,a tempera-ture control system based on pulse width modulation is designed for hemispherical resonator gyro in this paper.Through the selection of temperature control mode for gyro combination,uniform symmetrical structure design and thermal model modeling,the temperature control system of gyroscope is designed using FPGA.The experiment shows that the temperature control system has a precision of±0.1℃,which meets the performance requirements of the gyro.
