Abstract
The paper addresses a central question: What kind of information or measurements are needed for
closed loop control of distributed systems? Is it sufficient to deal with projections or do we need
tomographic data? The answer to these questions is strongly related to properties derived from
``observability'' and ``controllability'' of a process. It can be shown that under certain circumstances
both strategies can be equivalent (however not with respect to the computational complexity) and
for what conditions we will have different results. The theoretical results will be illustrated with
