| 摘 要： | 针对传统载体磁补偿求解系数存在病态性的问题,本文研究了磁干扰的主要来源,忽略了涡流场的影响,在原有的模型基础上进行了简化,建立了三分量磁补偿模型,由此提出了磁场分量的在线载体补偿方法。通过与传统方法进行对比仿真,本文方法有效提高了约1.14 nT的补偿精度。同时利用现场可编程逻辑门阵列(field programmable gate array,FPGA)的高层次综合工具(high-level synthesis, HLS)对该方法进行了嵌入式硬件仿真,验证了方法在硬件系统的实时性和补偿精度。

| Abstract: | Aiming at the ill-conditioned coefficients in the traditional carrier magnetic compensation, this study investigated the main source of magnetic interference, simplified the original model by ignoring the influence of the eddy current field, and established a three-component magnetic compensation model. Accordingly, it proposed an online carrier magnetic compensation method for the magnetic field components. Compared with the traditional method, the method proposed in this study effectively improved the compensation accuracy by about 1.14 nT. This study conducted embedded hardware simulations of this method using the high-level synthesis (HLS) tool of the field programmable gate array (FPGA), verifying the real-time performance and magnetic compensation accuracy of this method in a hardware system. |
