Some algebraic, combinatorial and algebraic-differential me-
thods have beenused in recent years in order to solve many
problems in control theory, by effective algorithms. Imple-
mentation of these algorithms generally involves algebraic
computation systems and tools. Software realizations are al-
ready developed in an increasing number of research centres.
The goal of the "First European Conference on Algebraic Com-
puting in Control" has been to present the main actual me-
thods for analysis and control of systems which naturally
lead to the use of algebraic computing.
The maintopics and themes are as follows:
mathematic tools in control theory that lead to effective
algorithms, algebraic computing tools, that are available in
the field of control theory, software realizations in
control involving algebraic computing.
