Abstract

It is shown that a method for the identification of deterministic systems derived from the Kalman filter is related to a gradient technique of parameter estimation and that the range of problems to which the gradient method may be applied is thereby extended. Various versions of the discrete-time algorithm are compared from theoretical and computational points of view and also contrasted with the continuous-time algorithm. An important outcome is that the system containing unknown parameters and the identification algorithm may be formulated with one in discrete-time and the other in continuous-time.
