Several engineering systems require isolation of sensitive equipment from foundation vibrations or isolation of the foundation from machinery vibrations. Even though passive vibration isolation systems are effective in reducing the amplification at resonance, high frequencies attenuation is poor. Active vibration isolation (AVI) systems are being used for eliminating this problem. AVI is essential in multiple axes for precision control of a wide range of space-borne structures and also for a

The design optimization is carried out using genetic algorithm by subjecting the model developed in 'MatLab'.
