In this paper we study the problem of the four-dimensional hyperchaotic Rossler system tracking control. A controller based on the reference signal is designed. It is theoretically proved that the controller can make the error converge to zero exponentially. Numerical results have verified the validity of the controller. The Rossler system cannot only track any reference signal fast, but can synchronize with identical or different chaotic systems.
