| 摘 要： | 基于区间分段思想,将极化曲线非线性参数辨识转化为两个线性最小二乘辨识子问题.MATLAB仿真表明,拟合曲线与模型数据及实验数据的平均二次误差,分别为开路电压的0.31%和0.75%,精度与牛顿法相当.

| Abstract: | The nonlinear parameter identification of fuel cell polarization curve was converted into two sub-problems of linear least square identification based on interval segmentation technique.The average quadratic error between fitting curve and model data was 0.31% and the error between fitting curve and experimental data was 0.75% of the open circuit voltage,which showed in MATLAB simulation,which were as accurate as the Newton method. |
