| 摘 要： | 针对无驱动结构微机械陀螺的工作带宽进行理论分析,提出一种调整频带宽度的方案。然后利用MATLAB和PSpice软件进行仿真验证,最后利用安捷伦信号发生器81150A对调整前后的电路部分进行实验验证。实验结果表明,通过调整后整个信号处理电路的带宽得到了扩展,使得陀螺在工作频率范围内的信号可以无衰减地通过。这里采用的实验方法是信号发生器的静电驱动动态扫频测试。这种方法与传统采用MEMS三轴转台测试方法相比,更加简便,准确。

| Abstract: | The work bandwidth for non-driven micro-machined gyroscope is analyzed in theory, presenting a scheme to adjust the bandwidth. Using MATLAB and PSpice software simulation to test, the Agilent signal generator 81150 A is applied to experiment to verify the circuit part of non-driven micro- machined gyroscope both before and after adjustment. The experimental results show that the work bandwidth of the signal processing circuit has extended after adjustment, and the signal of the gyro has no attenuation within the scope of the work frequency. Signal generator electrostatic drive frequency sweeping method is adopted in the experiment. Compared with the traditional method of using MEMS three-axis turntable, this method is more convenient and accurate. |
