Abstract: Parameter mismatch is the unavoidable problem of chaotic secure communication based on chaos synchronization technology.Taking the typical Lur’e delayed chaotic system as the research object,based on impulsive control method,we achieved modified function projective quasisynchronization of the drive-response chaotic system under the condition that there is a mismatch between the parameters of the drive system and the response system.Sufficient conditions were given for the quasisynchronization,and quasisynchronization error limit was also estimated.Finally,simulation results verify the validity and effectiveness of the theoretical analysis.

Key words: Modified function projective quasisynchronization,Delayed chaotic system,Parameter mismatch,Impulsive control
