摘　　要：基于MATLAB软件中的SIMULINK仿真环境建立了磁调制器的仿真模型,它可以精确模拟坡莫合金磁化曲线的饱和段,有效克服传统作图法的不足,能够快速分析包括激励线圈、直流偏磁线圈、检测线圈等的内阻在内的各种参数对调制性能的影响,有利于了解磁调制器工作机理,对于快速设计具有合理特性的磁调制器有指导意义。Simulation model of magnetic modulation comparator based on SIMULINK environment of MATLAB is built up.The model can exactly simulate the saturation of B-H curve of permalloy core,and overcome the shortage of traditional charting method.It takes into account the influence of the self-resistance of stimulation winding, direct winding and measurement winding.The presented method can give great help to know the operating mechanism of magnetic modulation comparator, which also is important to design the comparator with satisfactory performance.
