In this talk I consider some aspects involved in the analysis
and control of dynamic systems under symbolic command. Symbolic commands
are inputs to the dynamic systems which take values in a finite or countable
set, and arise in a wide variety of systems. Their occurrence may be due
to the nature of the system itself, or to technological limitations (such
as finite band with in networked embedded control systems), or may be intentionally
introduced to achieve more compact and efficient abstractions of possible
behaviours. I will overview recent results related to the analysis of reachability
for such systems, including a discussion of density/discreteness and lattice
structures of the reachable set, and an extension of the classical notion
of discrete nonholonomy. I will also point at some results and open research
directions concerning synthesis of planning strategies and optimization
for systems with symbolic inputs, and their stabilization.
