The sliding mode synchronization problem of Jafari-Sprott chaotic system was studied,and based on Ly-apunov stability theory and synchronization control related theories,we had provided research conclusions on syn-chronization control.Two schemes for implementing synchronization of Jafari-Sprott chaotic system had been pro-posed.The phase diagram of the attractor and the error curve of the system were drawn using MATLAB simulation technology,and the results obtained were verified numerically to determine the feasibility and effectiveness of the synchronization scheme.
