Abstract: A control method based on Projective Chaos Synchronisation (PCS) is developed for design of active seat suspension system. The chaotic vibration signals with broadband frequency are used to reduce the Power Spectrum Density (PSD) of the driver's acceleration in the human-body sensitive range. The scaling factor of PCS enables us to proportionally diminish the vibration amplitudes of the driver seat to the degree as we desire. Detailed analyses of this method show that the control method could improve the vibration-isolation performance effectively, and the control force applied to the seat suspension could be constrained to a relatively low level. In addition, the robustness of the control method is addressed.
