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

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
