A Guidebook on Jiles-Atherton Model Parameter Approximation Based on Simulated B-H Curves

This handbook and dataset provides a large set of ferromagnetic saturation curves with Hysteresis based on JA model and nonlinear reluctance of Matlab/Simulink/Simscape.The saturation curves are available for different materials, but for simulations, the JA parameters are also needed which are not available to the public. Therefore, this handbook will help researchers to find the best fit between their specimen and curves provided in this handbook to find the approximate JA parametes to use, or start fiding accurate JA using them as the initial values.本手册与数据集收录了基于JA模型（JA model）及Matlab/Simulink/Simscape非线性磁阻构建的大量带磁滞特性的铁磁饱和曲线。该类饱和曲线可适配多种不同材料，但开展仿真时还需配套的JA参数，而此类参数并未对外公开。因此，本手册可帮助研究人员将自身试样的相关数据与手册中提供的曲线进行最佳拟合，以获取可用的近似JA参数；或以该近似参数作为初始值，逐步开展精准JA参数的求解工作。
