摘　　要：文中在对H_∞估计问题进行数学描述的基础上,建立了一种H_∞次优滤波算法的迭代方程。通过在GPS/SINS组合导航系统中的实际应用从精度、鲁棒性等指标方面对H_∞滤波和Kalman滤波算法进行比较。仿真结果表明,在理想条件下,Kalman滤波方法具有较高的精度.但是,当系统噪声和量测噪声为有色噪声时,H_∞滤波算法明显具有良好的鲁棒性能,估计精度也较高,能有效地克服Kalman滤波器存在的局限性。An iterative equation to H_∞sub-optimal filtering algorithm is analyzed on the basis of mathematic description for H_∞estimation problems,some performance indexes of H_∞filtering algorithm and traditional Kalman filter is compared by using a GPS/SINS integrated system.,such as accuracy,robustness.The simulation results indicate that Kalman filter has better accuracy in ideal condition.But when the system noise and measure noise is the colored noise,H_∞filtering algorithm has better robustness and accuracy,o...
