为提高制导工具误差线性模型求解精度,基于优化模型,利用进化策略方法实现了对制导工具误差线性模型的求解,并研究了遥、外测数据随机误差对制导工具误差线性模型求解精度的影响。仿真结果表明,该方法优于主成分法,制导工具系统误差系数估计值与仿真均值之差均比标准差小3倍,遥测数据随机误差对环境函数的影响较小,遥外差数据随机误差对线性模型求解精度影响较大,制导工具系统误差的最大偏离真值量比标准差大1倍。
In order to improve the accuracy of the guidance linear error model of the guidance tool, based on the optimization model, the evolutionary strategy method is used to solve the error linear model of the guidance tool. The effects of the random errors of the guidance and measurement data on the accuracy of the guidance linear error model are also studied. The simulation results show that this method is superior to the principal component method, the difference between the estimated error of the guidance system and the simulation mean is less than 3 times of the standard deviation, the random error of the telemetry data has less effect on the environmental function, and the random error of the telemetry data Which greatly affects the accuracy of solving the linear model. The maximum deviation from the standard error of the guidance system is one times larger than the standard deviation.
