旋转载体用硅微机械陀螺的相位研究

Phase research of silicon micro-machined gyroscope using for rotating carrier

介绍了利用旋转载体自旋作为驱动力的硅微机械陀螺的结构和原理,通过对陀螺相位的处理来判断载体的偏转极性。用重力加速度计信号反映载体自旋信号作为基准,通过比较陀螺信号和加速度计信号的相位,再除去两者相位差中所含的滞后值,进而可以判断载体在空间中实际偏转方向。

The structure and principle of silicon micro-machined gyroscope used for rotating carrier is introduced. By processing gyroscope phase, the deflecting polarity of the carrier can be judged. Using the gravity accelerometer signal, which reflects the carrier＇ s rotation information, as the benchmark, comparing with the output signal phase of the accelerometer and the gyroscope, then subtracting the lagged value from the two phases difference, we can judge the real deflecting direction of the carrier in the space.
