A unified method for the projective synchronization of chaotic system is proposed in this paper. The universal model of chaotic projective synchronization is established by constructing a generalized proportion matrix and an appropriate response system. All kinds of synchronized schemes can be achieved by varying the generalized proportion matrix, including generalized projective synchronization, dislocated projective synchronization and generalized hybrid dislocated projective synchronization and so on. The stability analysis in the paper is proved using Lyapunov stability theory. Numerical simulations of generalized hybrid dislocated projective synchronization for multiscroll chaotic attractors system and hyperchaotic Qi system verify the effectiveness of the proposed method.
