We developed a new closed-open-loop optimal control algorithm that has been derived by minimizing the sum of quadratic time-dependent performance index and the seismic energy input to the structural system.This new algorithm has been in troduced to a model eight-story building to demonstrate reduction of vibrations caused by medium earthquakes. An active dynamic mass driver system driven by an AC servomotor through a ball screw was developed and installed at the top floor of the model structure. We have obtained the results that there were control paragmeters to maximize control efficiencies for a given structural system,and the proposed closed-open control algorithm could perform the same control efficiencies as the control algorithms based on the regulator theory. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
