In this paper, we investigate coupled quintessence with scaling potential assuming specific forms of the coupling as A namely, ,
and
, and present phase space analysis for three different interacting models. We focus on the attractor solutions that can give rise to late time acceleration with
of order unity in order to alleviate the coincidence problem.
