Abstract

This paper provides a complete derivation of the discrete-time H(infinity) controller and filter using a variation of parameters approach. We show that the H(infinity) filter has a similar structure to the Kalman filter. These results are consistent with existing derivations under alternative techniques. Conditions derived from the variational technique, which provide for filter existence, are presented. As an example, the Kalman, H(2), and H(infinity) filters are applied to the steady state target tracking problem where their performance is examined.
