Recursive least squares vs kalman filter
WebJun 8, 2024 · The (linear) least-square formulation reads for a set of observation y ∈ R q. with ϵ ∈ R q , C ∈ R q × n, L ∈ R q × q (weighting matrix) and x ∈ R n the state to be estimated. Kalman filter makes use of a dynamical model for the state and a linear mapping from the observation to the state. Where w k and v k (plant and measurement ...
