| Abstract: | A new chaotic system was constructed by changing the sign of the quadratic terms of the Liu chaotic system.Existence of chaotic behaviors was proved by Lyapunov exponents,equlibrias and dissipation.Based on the stability criterion of linear system,switched function projective synchronization was achieved by appropriate linear seperation method.The feasibility and validity of this method were verified through numerical simulation. |
| Keywords: | new chaotic system Lyapunov exponent linear separation modified function projective synchronization |
