摘要
为解决弹体姿态控制能力问题,对基于DSP的地磁陀螺组合测姿系统进行研究,将三轴MEMS陀螺与地磁组合成样机,基于旋转矢量法姿态算法和TMS320F28335进行数据处理,并进行转台试验,解算出不同转速下的滚转角并进行误差分析。试验结果表明:该方案能够实时、准确、稳定地处理陀螺和地磁信号并解算出姿态结果,满足姿态控制的要求。
In order to solve the problem of controlling ability of projectile＇s attitude, the system of geomagnetic gyro ,combination pose measurement based on DSP is studied. Use the prototype of tri-axial MEMS gyro and geomagnetic, based on rotation vector attitude algorithms and TMS320F28335 for data processing, calculating the roll angle under different rotational speed and analyzing error. Test results show that the scheme can process gyro and magnetic signals and calculate attitude results in real-time, accurately and stably, meet the requirements of attitude control.
