Abstract: In this article, an active-passive composite mass damper system for the vibration control of structures under harmonic base excitation is presented. Earlier studies by the Japanese research team of the Kajima Corporation have shown that such a composite damper system is significantly superior in reducing the peak structural response when compared to employing a single passive mass damper system. The important design aspects of this composite damper system are the appropriate supply of the control forcing function by the actuator and the mass damper parameters. The control forcing function is usually assumed as a linear combination of the structural and damper responses, with the coefficients being referred to as the feedback gains. The authors propose an optimization technique for determining the optimal values of the feedback gains and the damper parameters that minimize the peak structural displacement. They show that the set of feedback gains and damper parameters obtained from the proposed method leads to a greater reduction in the peak structural displacements than those obtained by earlier researchers.
