Summary:This paper deals with a control algorithm based on an optimal control theory for a hydraulic active mass damper (AMD) system, which is used to suppress vibrations of high-rise buildings caused by winds or earthquakes. A low-order linear approximation of the AMD system and a control algorithm are derived. In this control design, the damping ratio of the dominant pole is taken as an index of the control system, and modelling error does not have a significant effect on the stability of the system. This design algorithm was verified by experiments on a small-scale model.
