An Intelligent Tool for System Identification
1989
In: Proceedings of the 1989 IEEE Control Systems Society Workshop on Computer-Aided Control System Design. - Linköping : Linköping University. ; , s. 58-63
Reports (other academic/artistic) abstract
An application of the MaMiC programming environment (a programming environment for handling both numeric and symbolic data) is described. The application is an intelligent interface to MathWorks' System Identification Toolbox. The interface contains two parts: one that makes it easier to use the System Identification Toolbox (by simplifying the syntax and by bookkeeping of all variables used in the system), and one that gives the user advice during an identification session. A decision support system which advises the user only about the interpretation of certain results and how to do reasonable commands, actions, etc. is described and illustrated by an example.

System identification using high-order models, revisited
1989
In: Proceedings of the 28th IEEE Conference on Decision and Control. Part 1 (of 3). - Linköping : Linköping University. ; , s. 634-639
Conference paper (peer-reviewed) abstract
The traditional approach of expanding transfer functions and noise models in the delay operator to obtain predictor models linear in the parameters leads to approximations of very high order in the case of rapid sampling and/or large dispersion in time constants. By using a priori information about the time constants of the system, more appropriate expansions, closely related to Laguerre networks, are introduced and analyzed. It is shown that these expansions need much lower orders to obtain reasonable approximations and improve the numerical properties of the estimation algorithm. Consistency (error bounds), persistence of excitation conditions, and asymptotic statistical properties are investigated.

A decentralized virtual memory scheme implemented on an emulated multiprocessor
1989
In: Proceedings of the Twenty-Second Annual Hawaii International Conference on System Sciences. Vol.I. ; , s. 286-95
Conference paper (peer-reviewed) abstract
A decentralized scheme for virtual memory management on MIMD (multiple-instruction-multiple-data) multiprocessors with shared memory has been developed. Control and data structures are kept local to the processing elements (PE), which reduces the global traffic and makes a high degree of parallelism possible. Each of the PEs in the target architecture consists of a processor and part of the shared memory and is connected to the others by a common bus. The traditional approach, based on replication or sharing of data structures is not suitable in this case when the number of PEs is of the magnitude of 100. This is due to the excessive global traffic caused by consistency or mutual exclusion protocols. A variant of the Dennings working set page replacement algorithm is used, in which each process owns a page list. Shared pages are not present in more than one list, and it is shown that this will not increase the page fault rate in most cases.

A software system for defining and controlling actions in a mechanical system
1988
Licentiate thesis (other academic/artistic) abstract
This thesis deals with the subject of technical systems where machinery, usually of mechanical character, are controlled by a computer system. Sensors in the system provide information about a machine’s current state, and are crucial for the controlling computer. The thesis presents an architecture for such a software system and then describes the actual implementation along with some examples.
