Dead-beat styrning av en värme-diffusionsprocess
Identifiering av återkopplade system
The achievable accuracy of models derived by identification depends on a number of factors, e.g. the conditions during the experiments. The accuracy is studied by simulation for a number of different experiments: open loop experiments with different types of input signals and closed loop experiments with different types of regulators. For this purpose a special simulation program has been written
Dynamiska modeller för reningsverk
The purpose of this report is to study dynamic models of processes used in waste water treatment. The report consists of a literature study and identification of two different unit processes. The literature study consists of a thorough search of some relevant periodicals, and the result is presented as a collection of abstracts of articles, treating dynamic aspects of waste water treatment techno

Program för maximun-likelihood-identifiering på PDP-15
In this report a program for identification by the Maximum-Likelihood method is presented. The program is written in FORTRAN for a process computer, PDP-15. The application is limited to linear, single output, time-invariant dynamic systems with normal disturbances having rational spectra.

Matematisk modell för sjön Trummen
The purpose with mathematical models in ecology is 1) to help to create better understanding of ecological systems behaviour and 2) to make it possible to estimate more accurately the effects of human interference in nature.

A nonlinear dynamical model and control of the feed water system on a turbine tanker
In this report we present a non-linear mathematical model of the feed water system onboard a 250 000 ton dwt turbine tanker in the Kockum Hull 540-series (Esso Dalriada). Well-known relations from the theory of fluid mechanics give the main part of the model. A few equations are approximations of the manufacturer's data curves. The most important dynamical equations embrace acceleration of the
