| 摘 要： | 为了得到既有较强抗差性又有较高效率的估值,提出一种基于F a ir函数的抗差状态估计算法。抗差最小二乘估计通过等价权把抗差估计原理与加权最小二乘(W LS)形式有机结合起来,提出了将F a ir函数通过等价权应用于抗差估计,使抗差和状态估计在计算中一次完成。仿真算例表明,该方法可以有效减小或消除粗差的影响,收敛速度快。

| Abstract: | A new robust state estimation method based on Function of Fair is presented.Based on the principle of equivalent weights,the LRS method is combined with robust estimation theory and the WLS form.The Function of Fair is applied to robust estimation.This method can combine outlier resistance and state estimation in one calculation process.Digital simulations indicate that the method is efficient in decreasing or diminishing the influence of gross error,and has high convergence speed. |

| Keywords: | least robustness square(LRS) weighted least square(WLS) Function of Fair state estimation gross errors |
