Abstract
We prove the exact controllability by boundary action of hyperbolic in terface problems with singularities. The idea is to replace the classi cal space of controls with the space of their regular parts, which is augmented with the coefficents of singularities. This leads to a class ical boundary control but with an internal control, which is a distrib ution with a support equal to the singular vertices.
