This paper presents a hybrid control system composed of an active hydraulic actuator and a passive liquid-mass damper. The system is built with structural bracing and can reduce structural dynamic response by providing passive inertia force, passive damping force and active control force. Fundamental equations governing the hybrid control system are derived and influence parameters are numerically analyzed. Numerical results show that in this hybrid control system the effective liquid-mass plays an important role in reducing structural dynamic response and requiring smaller control forces than either passive or active control system.
