鉴于传统圆锥误差补偿算法中忽略圆锥运动的幅值特性,并且存在泰勒级数高阶项截断误差的问题,基于传统圆锥误差补偿算法公式,通过载体不同的机动性能指标确定圆锥运动幅值特性,并利用最小二乘方法估计一组圆锥补偿算法的加权系数,从而得到一种新的捷联惯导系统圆锥误差补偿算法,仿真结果表明,文中算法对圆锥误差补偿效果优于传统算法.
Considering that classic coning error compensation algorithm ignores amplitude characteristic of coning motion and exists trunca- tion error of Taylor series high order items, in the paper minimum least-square estimation was applied to deduce weighting coefficients of er- ror compensation algorithm by considering amplitude characteristic of coning motion which can be determined by different performance re- quirements of carrier. The simulation experiment result shows that the new algorithm is better than classic algorithm for effect of coning error compensation.
