Abstract

In this paper, the tracking control and generalized projective synchronization of a class of hyperchaotic system with unknown parameter and disturbance are investigated. Based on the LaSalle’s invariant set theorem, a robust adaptive controller is contrived to acquire tracking control and generalized projective synchronization and parameter identification simultaneously. It is proved theoretically that the proposed scheme can allow us to drive the hyperchaotic system to any desired reference signals, including hyperchaotic signals, chaotic signals, periodic orbits or fixed value by the given scaling factor. The presented simulation results further demonstrate that the proposed method is effective and robust.

► In this paper, we combined generalized projective synchronization with tracking control ingeniously. ► The proposed scheme is suitable for a class of hyperchaotic systems with unknown parameters and disturbance. ► The proposed scheme is robust to the external disturbances and can identify the fully uncertain parameters simultaneously.
