| Abstract: | 3-DOF vibration reduction platform using 3-PRRP~(|(4r)) parallel mechanism and the elastic damping devices were established. A semi-active controller was designed with LQR law to control the system. Then, an experiment system was constructed to test the vibration of on control and off control. The result showed that it has good effectiveness for multi-dimension vibration control of instrument carried in vehicle. |
