| 中文摘要 | 磁通门信号处理电路作为磁通门磁场测量的重要组成部分,其电路参数的设计选择直接影响了测量的精度、时效性和稳定性。在分析磁通门测量原理的基础上,设计制作了磁通门信号处理电路;在综合考虑探头灵敏度和功耗下,得到在6.25 kHz的正弦激励下,较优的激励电压峰峰值为14.5 V;通过对信号处理电路各环节的建模及简化分析,得出信号处理电路系统为一个二阶Ⅰ型系统,并通过实验方法测定了开环比例系数,然后按最优二阶模型,对其进行了优化设计。最后,对所设计制作电路进行了稳定性和重复性实验,得到稳定性精度为6.1 nT(1σ),重复性精度为13.05 nT(1σ),精度满足多数磁导航应用要求。; As an important part of fluxgate magnetic field measurement,the fluxgate signal processing circuit directly influences the effectiveness,stability and precision of measurement.On the basis of analyzing the fluxgate principles,the fluxgate signal processing circuit is designed and realized.Considering the probe sensitivity and consumption,the near optimal peak to peak of sinusoidal excitation voltage is 14.5 V,with the 6.25 kHz frequency.According to the simplified analysis and modeling for each circuit link,it is concluded that the signal processing system is a second-order system,and the open loop proportional coefficient is determined by experimental methods.Then according to the optimal second-order model,the optimization design is carried on.Finally,the designed circuit is statically tested,and the results show that stability precision is 6.1 nT(1 σ),repetitive precision is 13.05 nT(1σ),which can satisfy the requirements of many magnetic navigation applications. |
