  • In this paper, based on output linearization feedback control,the nonlinear function of the chaotic system is linearized, then the complex synchronization of the nonlinear chaotic system is converted into the stable problem of the linearization system. Then a nonlinear controller is given by pole assignment. Furthermore based on the scheme above, a system of secure communication is proposed. One channel of the system is output of the chaotic transmitter, the other one transmits the information-bearing signal. Finally a numerical example is used to show the effectiveness of the proposed technique.
