It is well known that the output error and Box-Jenkins model structures cannot be used for prediction error identification of unstable systems. The reason for this is that the predictors in this case generically will be unstable. Typically, this prob

We investigate whether it is possible to synthesize the control law for a discrete event dynamic system, using a polynomial representation of the system and controller. By working through a relatively simple example we propose a synthesis method base

The usefulness of frequency domain interpretations in linear systems is well known. In this contribution the connections between frequency domain and time domain expressions are discussed. In particular, the author considers some aspects of using fre

Terrain navigation is an application where inference between conceptually different sensors is performed recursively online. In this work the Bayesian framework of statistical inference is applied to this recursive estimation problem. Three algorithm

Switched bond graphs are natural extensions of classical bond graphs and they allow mod eling of hybrid systems If using switched bond graphs there is an extension to the mechanical momentum This extension called generalized momentum includes eg char

In this paper we will consider the derivative causality as a consequence of simplifying the model by neglecting energy dissipation If the energy dissipation is small enough it is a natural model simplication to remove it from the model To allow gener

Maximum likelihood estimation of single-input/single-output linear timeinvariant (LTI) dynamic models requires that the model innovations (the nonmeasurable white noise source that is assumed to be the source of the randomness of the system) can be c

Integral quadratic constraints (IQC:s) can be used for proving stability of systems with uncertainties and nonlinearities. Similarly, IQC:s can also be used for controller synthesis. Necessary and sufficient conditions for the existence of such a con
