PC-styrning av fjärrvärmeverk

This master thesis describes a graduation work that was carried out on a heating plant owned by Sydbränsle AB. It describes the resulting control system, the way to final resolutions and conclusions. The goal was the usage of a PC as an operator interface to simplify the supervising and controlling of the heating plant. Man/machine interface would be simplified extensibly so that all the untrained

Adaptive Control of Piecewise Linear Systems

This thesis treats several problems in control of piecewise linear systems. A parameter estimation algorithm for piecewise linear systems is presented. Some problems with the algorithm are discussed and suggestions with regard to the input requirements are made in order to overcome the problems encountered. A self-tuning regulator for piecewise linear systems is presented, using pole placement des

Styrning av missil med hjälp av multimodellering

This report investigates the possibility of simulating the cruising of a missile by using the program Matlab and SimuLink. Matlab is a mathematical package with a number of application areas, for instance statistics, signalling and control theory. SimuLink is an easy to-use program package for building models and for simulation of both linear and non-linear technical control systems. The report d

Reglering av autoklav

In this master thesis, the problem of finding a suitable controller that can adapt to different sterilization environments is treated. Most of the work is based on the problem of finding a way to mathematically describe the process. The sterilizer that is analyzed is a steam pressure autoclave which is supposed to work at a temperature between 121 degrees celsius and 135 degrees celsius. A suggest
