Abstract
We study the scenario of dark energy model that constructed by combination of scalar fields from quintessence and nonminimal derivative coupling terms. We assumed that there will be exchange between the scalar fields of quintessence and nonminimal derivative coupling and the ordinary matter do not explicitly coupled with the dark sector. Using the dynamical system analysis, we determine the stability of our model and find the attractor solution.
