WebThe guarantees of the Kalman filter (KF) only apply to linear systems. We linearize a non-linear system in hopes of retaining some of those guarantees for non-linear systems. In fact linearizing the non-linear components of a system (i.e. the motion model and/or the observation model) is the very thing that differentiates KFs and EFKs.
