| Abstract: | In this paper, the dynamical analysis is performed for a spatially flat universe governed by a special model off（R, T） gravity. The critical points are elassifled and a three-dimensional attractor is found. Especially, in the case of T = O,the phase portrait is plotted for the two-dimensional autonomous system. |

| Keywords: | modified gravity theory attractor the phase portrait |
