A research of fuzzy Kalman filter algorithm based on GPS/DR integrated navigation system

摘要

In this paper, according to working environment and application requirements of vehicle integrated navigation system, it takes GPS/DR vehicle integrated navigation system as the application object, it combined fuzzy theory and Kalman filter algorithm; and then a fuzzy Kalman filter was developed. It shows that by simulation experiments, this algorithm can suppress filter divergent-factors and improve anti-interference ability, and robustness effectively. This filter algorithm can adapt the change of noise environments.
