摘要:: 针对自适应渐消因子卡尔曼滤波无法应用于非线性系统的问题以及自适应渐消因子的局限性，提出了带自适应渐消矩阵的扩维UKF(adaptive fading matrix augmented UKF, AFMAUKF)算法．该算法针对含有非加性白噪声的非线性系统，引入了一种新的自适应渐消矩阵计算方法，并用Unscented变换逼近系统的后验均值和协方差，有效解决了此类系统的滤波问题．针对SINS/GPS组合导航系统的非线性状态估计问题，分别设计了滤波器容错试验和系统噪声突变试验，试验结果证明了该算法的有效性．

Abstract:: Because an adaptive fading Kalman filter cannot be applied to nonlinear systems, an augmented unscented Kalman filter (AUKF) based on an adaptive fading matrix (AFM) was proposed in this paper. The AFMAUKF algorithm was implemented by first calculating the adaptive fading matrix, and then using the unscented transformation to estimate the posterior mean and covariance of the state of a nonlinear system, so as to effectively solve the filtering problem. In order to solve the problem of nonlinear state estimation in a lowcost integrated navigation system, a filter faulttolerant experiment and a system noise mutation experiment were designed and implemented, respectively. The experimental results prove that the algorithm enhances the robustness of the filter when the system model is uncertain, improves the accuracy of the filter, and has a strong faulttolerant ability.
