Abstract :
A finite-dimensional observer theory is formulated for a class of point delayed systems. The observer is characterized by the fact that it directly generates a finite-dimensional feedback controller for this class of systems. The theory is based on a preliminary approximation theory which allows the delay system to be exponentially approximated by a system of ordinary differential equations.
