Abstract

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.
