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

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

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

This volume describes a study of different methods for identifying systems operating in closed loop. The results are to be applied on power generating systems.

This report is the documentation of a project called "A Process Knowledge Base Browser", that has been performed as a Master Thesis in Computer Engineering at the Lund Institute of Technology.

An important function for the human body is the ability to maintain balance. This has been compared to a sixth sense whose function we would have difficulties to be without. The system of balance is a complex system which uses several different sensors to get a satisfactory image of the position and motion of the body. One of the sensors is vision. Our assignment has been to make an equipment for

When measuring transient behaviour in descrete time, limitations in memory size impose truncation errors on the computations performed in the subsequent analysis of data. In this paper different approached to minimize or avoid these errors are investigated.

Identification of process dynamics is used for stability monitoring in nuclear reactors (Boiling Water Reactor). This report treats the problem of estimating a damping factor and a resonance frequency from the neutron flux as measured in the reactor. A new parametric online method for identification is derived and presented, and is shown to meet the requirements of stability monitoring. The techni
