摘要:

为了控制并提高压电半球谐振陀螺仪的检测精度,采用力反馈模式下的驱动检测方法实现了基于现场可编程门阵列(FPGA)的半球谐振陀螺数字式闭环测控系统,并完成了硬件实现。最后,通过对数字测控系统的仿真和转台测试实验,得到陀螺标度因数为1.428mV/(°/s),验证了此方法的有效性。

Abstract:

In order to control and improve the detection accuracy of the piezoelectric hemisphere resonant gyroscope, a driving and detection method in force feedback mode was adopted to realize the hemispherical resonator gyro digital closed-loop measurement and control system based on FPGA. And the hardware design was implemented. Simulations on the digital detection and control system were performed, and the scale factor of the gyro was 1.428mV/(°/s), verifying the validation of this method.
