Abstract

The problem of exact boundary controllability of semi-linear one-dimensional heat equations is investigated. It is proven that it is possible to move from any steady state to any other one by means of a boundary control, provided that they are in the same connected component of the set of steady states. The proof is based on an effective feedback stabilization procedure which is implemented.
