In this paper, a hybrid method using active control and a High Order Differentiator (HOD)
methodology is proposed to synchronize chaotic systems. Compared to some traditional
active control methods, this new method can synchronize chaotic systems where only output
states of the master system are available, i.e. the system is considered a black box. The
HOD is used to estimate the derivative information of the master system followed by an
active control methodology relying on HOD information. The Qi hyperchaotic system is
used to verify the performance of this hybrid method. The proposed method is also compared
to some traditional methods. Experimental results show that the proposed method
has high synchronization precision and speed and is robust against uncertainties in the
master system. The circus implements of the proposed synchronizing scheme are included
in this paper. The simulation results show the feasibility of the proposed scheme.
