Webb5 mars 2024 · The simplest formulation of a Kalman filter [ 1] is when the state and measurement equations are both linear. However, Kalman filter has found its greatest application for non-linear systems. A typical continuous state with discrete measurements in time forming a non-linear filtering problem can be written as x k = f x k − 1 Θ u k − 1 + … WebbMethod 1 on the other hand has assumed the following model for the velocity dynamics: v k + 1 = v k i.e. assumed that the velocity is constant. The problem here is the filtering performance is dependent on the validity of this model and the initial state estimate.
