摘　　要：为提高传递对准的精确性和鲁棒性,将H∞滤波和粒子滤波运用到SINS动基座传递对准,并对H∞滤波和粒子滤波应用于传递对准的鲁棒效果进行了比较。仿真结果表明,在有色噪声和白噪声强度较小时,两种滤波方法的滤波精度差别不大,但当有色噪声和白噪声强度较大时,粒子滤波精度优于H∞滤波。并且就估计精度而言,其鲁棒性优于H∞滤波,但H∞滤波的估计速度优于粒子滤波。H∞ Filtering and panicle filtering are applied to transfer alignment of missile SINS on moving base for improving robust performance and accuracy, and the robust performances of H∞ filtering and particle filtering are compared in transfer alignment. Simulation results show that when color noise intensity and white noise intensity are small, the two filters achieve almost the same accuracy; and when color noise intensity and white noise intensity are big, panicle filtering achieves higher accuracy than that of H∞ filtering. Particle filter is superior to H∞ falter in terms of estimate accuracy, but H∞ filtering is superior to particle filtering in terms of estimate speed.
