| Popis: |
A vibration isolation platform designed to attenuate high frequency vibration is proposed consisting of an active layer driven by a piezoelectric actuator and a passive layer. The proposed platform can achieve vibration isolation both in the vertical and horizontal directions. The dynamic behavior of the system is analyzed by deriving the equations of motions using the Lagrangian approach. System identifications are performed to validate the plant dynamics. The robust H¥ controller is adopted to design the controller with consideration of payload uncertainties. Experimental results show that the control can reduce vibrations by an average of 10dB within a frequency range of 15-40Hz. |
