摘要
针对初始对准过程中对准精度与快速性相矛盾的问题,提出并设计了把扩张状态观测器(ESO)与卡尔曼滤波滤波估计器相结合,用于捷联惯导系统初始对准的方法。数值仿真结果表明,该方法使对准过程所需要的时间大大缩短,并保证了较高的对准精度及较强的鲁棒性。
A fast initial alignment method for SINS is proposed which combines Extended States Observers(ESO) with Kalman filters. The method makes initial alignment more quickly than before and possesses such characters as high accurate and robust,etc. The simulation results demonstrate that it is an effective initial alignment scheme in inertial navigation system.
