| 摘 要： | 从无驱动硅微机械陀螺的敏感结构原理出发,对它的输出信号特征进行了分析,建立了相应的数学模型,提出使用最小均方差(LMSD)的算法对输出信号进行解调。使用MATLAB的数据处理方法,对仿真转台上得到的波形数据进行数字解调,将得到的结果与实际输入相比较,结果表明采用LMSD算法能够解调出陀螺的俯仰和偏航角速度信号。

| Abstract: | By analyzing the output signal of the non-drive micromachined gyroscope,a corresponding mathematical module was established with the principle of sensing structure.Utilizing this module,the digital demodulation method was discussed and the LMSD(least mean square demodulation) algorithm was introduced for the demodulation of gyroscope signal.Sampling signal date from the emulation turnplate and demodulating with MATLAB digital processing,an ascertain result can be found.Compared with practical input,it shows that the ameliorative LMSD algorithm is fit for the demodulation of gyroscope correctly,because both pitching and yaw rate signal can be obtained. |
