摘　　要：为解决MEMS电子罗盘易受强磁干扰影响导致其航向解算失准的问题,结合两种多目标优化算法与COMSOL有限元仿真,设计了一种优化的三维补偿线圈结构。首先根据Helmholtz线圈工作原理,在COMSOL软件环境中进行3D建模,设计正交试验初步设定了各组线圈参数,并简单分析了三维线圈的磁场梯度分布特性。通过COMSOL和MATLAB联合仿真,设置了线圈优化的目标函数和约束条件,分别运用NSGA-Ⅱ与MOPSO两种算法进行求解,并确定了线圈的实际结构参数。仿真结果表明该三维线圈能满足强磁补偿需求,具有较高的补偿效率。In order to solve the problem that the MEMS electronic compass is susceptible to strong magnetic interference and causes its heading to be inaccurate, an optimized three-dimensional compensation coil structure is designed by combining two multi-objective optimization algorithms and COMSOL finite element simulation. First, according to the working principle of Helmholtz coil, we carried out 3D modeling in the COMSOL software environment, designed orthogonal experiments to preliminarily set the parameters of each group of coils, and simply analyzed the magnetic field gradient distribution characteristics of the three-dimensional coil. Through COMSOL and MATLAB co-simulation, the objective function and constraint conditions of coil optimization are given, and the two algorithms of NSGA-Ⅱ and MOPSO are used to solve the problems, and the actual structure parameters of the coil are determined. The simulation results show that the three-dimensional coil can meet the needs of strong magnetic compensation and has high compensation efficiency.
