With the advent of materials, such as electrorheological fluids, whose material prop erties can be altered rapidly by means of external stimuli, employing such materials as actuators for the controlled attenuation of undesirable vibrations is now possible. Such control schemes are dubbed semiactive in that they attenuate vibrations whether applied actively or passively. We in vestigate various such control schemes, allowing for both separate and joint control of the stiffness and damping characteristics of the material.
