为精确确定舰炮武器系统的实际回转中心,以提高基线误差的修正精度,建立了回转运动轨迹的优化拟合模型,引入微分进化算法对拟合参数进行优化;分析了影响回转中心拟合精度的因素。实验结果表明,对于数据量少、相对长度较短的回转轨迹,微分进化拟合方法能有效提高回转中心的拟合精度。

To accurately measuring the true rotary center of the shipborne gun weapon system for improving the reference line correction accuracy, the optimal fitting model of the rotary motion trajectory is derived.The differential evolution algorithm is proposed to optimize the fitting parameters,then the factors affected the fitting accuracy of the rotary center are analysed.The experimental results show that the differential evolution fitting method can improve the fitting accuracy effectively for the rotary motion trajectory with less data points and short relative length.
