In this paper,the hybrid control of a viscoelastic structure with base-isolation has been researched.The energy dissipation ability of the visco-elastic damper is simulated by KELVIN model.Based on the modern control theories,the differential equations of the motion of the hybrid controlled structure are derived with dynamic simulation carried out through the MATLAB.The study results show that the hybrid control for the base-isolation structure with viscoelastic damper can improve efficiency of control for vibration.
