Six DOF active vibration control using stewart platform with non-cubic configuration

This paper focus on the design and active vibration control problem of flexure jointed stewart platform with non-cubic configuration. A general stewart platform is developed with non-cubic configuration using flexure mounts for all joints and magnetostrictive actuators as active elements, which leads to strong coupled motions along different axes. Adaptive filter algorithms for active vibration control are employed and realtime control system based on DSP controller are developed and implemented. Experimental results show that about 23-30dB attenuation is achieved.
