虚拟陀螺技术在MEMS惯性导航系统中的应用OA北大核心CSCDCSTPCD
Virtual gyro technique applied in the MEMS INS
针对MEMS惯性导航系统中陀螺测量精度低的问题,采用虚拟陀螺技术提高陀螺的角速度测量精度.系统中每个测量轴放置了3个普通精度的陀螺,组成一个阵列,对同一角速度信号进行冗余检测,然后通过同类传感器信息融合技术得到输入角速率的高精度估计值.试验结果表明,虚拟陀螺的精度最大提高了2.7倍,最小1.9倍,证明了虚拟陀螺技术的有效性.
To improve the measurement precision of micro-electro-mechanical systems (MEMS) gyros, virtual gyro techniques were used to test a miniaturized inertial measurement unit (MIMU) that the authors designed. The system arrayed three gyros of moderate precision on each axis to provide redundant signals at the same angular rate. Then through sensor information fusion technology, sophisticated homogeneous estimated values of input angular rates were calculated. The…查看全部>>
