Abstract :
The paper considers the continuous-time and discrete-time Kalman filters under noise uncertainties. The influence of these uncertainties on the filter performance can be characterized by the so-called sensitivity functions. Different ways for defining sensitivity functions are proposed and relationships for the corresponding functions are derived with the aid of matrix derivatives and finite differences. The results are illustrated with examples
