Flow Systems

  • K J Åström


An attractive idea when investigating large systems is to mimic the success of statistical mechanics, i e to consider a large system composed of many copies of identical subsystems. A fundamental difficulty is that it is hard to find meaningful systemtheoretic problems which can be obtained by interconnecting identical subsystems. This paper therefore considers a class of linear systems called flow systems. Although the systems are not identical many of their properties remain invariant for different interconnections, Flow systems can therefore be used as a starting point for analysing certain large systems. Flow systems have been used as models for industrial and biological processes.
