Application of Fuzzy Logic to Automatic Control: A Case Study of the Inverted Pendulum Problem

Implementation of Petri-Net and Grafcet Primitives in Omola and Modelling of Markov-processes

Automatisk viktreglering av ubåt med olinjära systemkomponenter

This is a presentation of automatic weight control of a submarine, where the use of nonlinear system components has been considered. The work was done at Lund Institute of Technology, Department of Automatic Control, with Kockums Marine, Malmö as sponsoring organization. The nonlinearities are due to the use of OnOff pump in the controller. This presentation consists of five different controllers.

A Reasoning Machine Generator for Object-Oriented Programming Languages

No title

The work is concerned with analysis of a method for robust adaptive regulation without persistent excitation presented by R. Lozano-Leal. The method is based on a least square identification algorithm with a dead zone. The dead zone is calculated from the covariance matrix and from the convergence of the parameter estimation. A convergence proof gives explicit bounds on the plant output. This wor

Modellbygge och simulering av värmebatteri

The purpose of this master thesis has been to find a simulation model for a crossflow heat exchanger in an air conditioning plant. The air temperature was controlled by changing the relation between hot water and recirculated water from the heat exchanger. The model which was obtained partly from literature studies was based on physical relations describing the heat transfer and energy balance. Th

Reglering av lödda värmeväxlare för ångapplikationer

We have, on Alfa Laval's behalf, tried out suitable control equipment to control the Brazed Heat Exchanger in steam applications. Reports have come in from several countries telling us about problems occuring when trying to control steam. Damages have arisen (often as a crack in the first or the last plate) due to fatigue caused by pressure variations in the steampipe. We have through a market

Implementering av en fuzzyregulator

The report refers to a master thesis project which has been done at SattControl AB and the Institute of Technology in Lund. The purpose of the project was to implement a fuzzy controller in SattLine, a new system of SattControl.

Service Restoration in Electric Power Distribution Networks

Automatic service restoration in distributional networks has been studied. After a thorough examination of the literature in this field, one algorithm was selected and implemented as a Fortran program. This implementation was then proved to be effective. Further improvements to the algorithm was introduced and in three cases these proved to be successful. For example: An operational aid indicating
