摘要：
This article heats the modified function projective synchronization between the hyperchaotic Lorenz-Stenflo (LS) system and a novel hyperchaotic CYQY system, and also that between the LS system and hyperchaotic Chen system, which have completely unknown parameters. By utilizing Lyapunov stability theory and active control method, the adaptive controllers and parameter update laws are derived to make the states of different hyperchaotic systems to attain adaptive modified function projective synchronization The system's unknown parameters can be identified simultaneously Numerical simulations are presented to demonstrate the effectiveness of the proposed methods
