Model Reduction of Positive Systems
University essay from Lunds universitet/Institutionen för reglerteknik
Abstract: The present work is concerned with the model order reduction of positive linear systems. Generally, well-established model reduction methods applied to positive systems do not guarantee the positivity of the approximation. To this end we examine som of the reasons for this behaviour and present a new method based on Balanced Truncation. Further, we compare the results of this approach with those of reduction methods especially developed for positive linear systems.
