In this paper, we present a dynamical analysis for a coupled tachyonic dark energy with dark matter. The tachyonic field phi is considered in the presence of barotropic fluids (matter and radiation) and the autonomous system due to the evolution equations is studied. The three cosmological eras (radiation, matter and dark energy) are described through the critical points, for a generic potential V (phi).
