摘要
在稳态卡尔曼滤波算法中引入非线性项 ,改进了算法的性能。思路是在姿态确定误差较大时 ,使得非线性滤波算法等价于具有较大滤波增益的稳态卡尔曼滤波器。理论分析和仿真结果表明在保证同样稳态估计精度的情况下 ,与稳态卡尔曼滤波算法相比较 。
A nonlinear algorithm for satellite attitude determination is developed. The main idea is to use the stationary Kalman filtering with higher gain, as the measurement errors are greater. The results of numerical simulation show that the above method is effective.
