Abstract

In many practical applications, the prior statistics of process and measurement noises are inaccurate, and the heavy-tailed distributed noises are prone to occur due to outliers. To achieve state estimation under this situation, a new outlier-robust Kalman filter with Gaussian multi-scale mixture model (GMSMM-ORKF) is proposed. First, a GMSMM is presented to model the posterior probability density functions. Then, the hierarchical prior models on the mixture probability vectors and scale parameters are built. Furthermore, employing variational Bayesian inference, a GMSMM-ORKF is derived. Finally, the superiority of the filter is illustrated by the simulation and real data.
