舰载导弹的动基座对准

本文将状态与偏差解耦卡尔曼滤波器应用于动基座对准中，根据舰载导弹动基座对准的特点，引入闭环，即在滤波过程中周期性地将滤波值补偿姿态失调角、速度误差和惯性元件误差。仿真结果表明，该方法能使收敛速度加快，估计精度提高，滤波值的振荡幅度减小。

Movable Base Alignment of Shipbased Missile

In this paper, a bias state decoupling kalman filter is applied to alignment of movable base. Based on the features of movable base alignment of shipbased missile,a closed looP is led in, i.e., in the filtering process,the filtered value is periodically used to compensate malfunction of the attitude angle,speed error and inertia element error.Simulation results show that the method quickenes convergence speed, increases estimation accuracy and decreases oscillating magnitude of the filtered value.
