Abstract
Multiple degree-of-freedom (DOF) vibration isolation is essential for precision control of
space-borne structures and weapon systems. A new design and analysis of actuators employing
magnetostrictive material TbDyFe is presented. Then, this paper studies the design and control
problems of a six DOF Stewart platform using the concept of cubic configuration. Optimal geometry
for the sensor configuration to get best signal is designed. To control the smart structure, a real time
computer control system is built. Improved robust adaptive filtering algorithm based on nonlinear
constitutive relation proposed in this paper and used in the computer control system. More than 20 dB
of vibration attenuation is achieved in real-time experiments.
