Apply modified projective synchronization to nonlinear vibration isolation system

One method was proposed which realize the modified projective synchronization between two degree nonlinear vibration isolation system and four dimension chaos system based on active control, in order to solve the conflict between the linear spectra reduction based on chaotifiy vibration responses and the capability of vibration isolation. The effectiveness of the proposed scheme was validated by the numerical simulation, which can achieve linear spectra reduction and proportionally diminish the vibration amplitude of isolated equipment.
