本文提出一种用于某单自由度液浮积分陀螺的二元脉冲调宽力反馈电路方案,并给出方案设计的具体实现过程、仿真分析以及实测结果。通过对比在同样试验条件下的测试数据,本文设计的基于FPGA二元脉冲调宽力反馈电路的测试精度略高于常用的数字电压表检测方法,因此可独立完成高精度测试而不需依赖其他辅助测试仪器。而且该电路采用数字化FPGA方案,针对不同测试要求,可以较灵活提高脉冲分辨率和采样频率,测试状态更接近陀螺的使用条件。 In this paper, we propose a binary pulse width-modulated feedback circuit for a single-degree-of-freedom liquid-floated integrated gyroscope, and give the concrete realization process, simulation analysis and measured results of the scheme design. By comparing the test data under the same test conditions, the test accuracy of the FPGA-based binary pulse width-modulated feedback circuit designed in this paper is slightly higher than the commonly used digital voltmeter detection method, so high-precision testing can be done independently without relying on other Auxiliary test equipment. And the circuit uses digital FPGA program, for different test requirements, you can more flexible to improve the pulse resolution and sampling frequency, the test state closer to the conditions of the use of the gyro.
