Sammanfattning : The recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. LÄS MER
2. Modelling, Analysis, and Control Aspects of a Rotating Power Electronic Brushless Doubly-Fed Induction Generator
Sammanfattning : This thesis deals with the modeling, analysis and control of a novel brushlessgenerator for wind power application. The generator is named as rotatingpower electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G).A great advantage of the RPE-BDFIG is that the slip power recoveryis realized in a brushless manner.

Sammanfattning : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

4. On Power Electronics Interface for Distributed Generation Applications and its Impact on System Reliability to Customers
Sammanfattning : Distributed generation (DG) is being employed as a means of achieving increased reliability for electrical power systems as regarded by consumers. As the most of DG technologies utilize renewable sources, the power electronic interface plays a vital role to match the characteristics of a DG unit with the grid requirements. LÄS MER
Sammanfattning : Cyclic computations under real-time constraints naturally occur in systems which use periodic sampling to approximate continuous signals for processing in a computer. In complex control systems, often with a high degree of autonomy, there is a need to combine this type of processing with symbolic computations for supervision and coordination. LÄS MER
