Generalized projective synchronization of a class of hyperchaotic systems based on state observer

In this paper, the generalized projective synchronization of a class of hyperchaotic systems is studied. On the basis of the state observer, it is not necessary to calculate the Lyapunov exponents, which makes this scheme simpler. Hyperchaotic Lü system and hyperchaotic Rössler systems are used as examples to validate the effectiveness of the proposed method.

► GPS for a class of hyperchaotic systems.
► Based on state observer, calculation of the Lyapunov exponents is not necessary.
► GPS has good application prospects in secure communication.
