| Abstract: | The piecewise four-dimensional continuous autonomous chaotic system is studied.The new system contains six system parameters and three quadratic cross-product terms.Based on Lyapunov stabilization theorem,and hybrid synchronization and nonlinear feedback control method,the sufficient conditions and range of the controller's parameter for self-synchronization of chaotic systems are derived.Matlab simulation results show the phase diagrams and error between driver system and response system.The orbit of the r... |
