THE FIXED-LAG SMOOTHER AS A KALMAN FILTER The starting point for fixed-lag smoother design using the filtering results of the previous section is clearly the definition of a signal process model. For fixed-lag smoothing where the fixed-lag is N time intervals, the state to be filtered is simply the original state delayed by the amount of the ... WebIn this paper, a novel state estimation approach based on the variational Bayesian adaptive Kalman filter (VBAKF) and road classification is proposed for a suspension system with time-varying and unknown noise covariance. Using the VB approach, the time-varying noise covariance can be inferred from the inverse-Wishart distribution and then optimized state … bison party supplies
