摘要
针对捷联惯性测量组合误差的数学模型,提出了惯性组合误差补偿的计算方法,推导了计算过程,得到了陀螺和加速度计误差补偿公式。通过补偿计算,能够得到弹体在采样时间间隔内运动的视速度增量和角增量。该算法能够满足应用的精度要求,对捷联惯性测量系统的误差补偿有一定的有效性和可行性。
An error compensation algorithm was presented for the mathematical model of strapdown inertial measurement unit,and the formulae for compensating the device error of gyroscope and accelerometer were given.The visual-velocity increment and angle increment of missile body between samplings could be obtained by compensation algorithm.The algorithm can meet the precision requirement in application,and is effective and feasible in error compensation of strapdown inertial measurement system.
