Synchronization of the Modified Chua's Circuits with a Derivative Filter

A novel derivative filter is firstly proposed in this paper and it is used in the synchronization of Chua’s Chaotic system with unknown parameters. It is described with transfer function so it makes use of the advantage of classical control theory. Also, it can absorb the merit of the modern control theory such as Lyapunov stability theorem. But the defect of this paper is that this paper is based on the assumption that three parameters in filters are small enough. So in our future work, a new analysis method will be researched which can relax this assumption.
