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

摘要

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 Lu system and hyperchaotic Rossler systems are used as examples to validate the effectiveness of the proposed method.
