Abstract: Duffing equation is a kind of important power system.The mathematic model of this system was studied in this paper.Structure of this system was changed with the variable decomposition method,and it was also proved that applying Duffing system with new structure to realize chaotic masking is rational.At the end of this paper,the running tracks of new Duffing system and the demodulation results of chaotic masking were given.Simulation results show that the method proposed here is correct and effective.
