| Research Abstract |
To realize a practical control device of active mass driver (AMD) type for high-rise buildings we developed a new closed-open-loop optimal control algorithm that has been derived by minimizing the sum of the quadratic time-dependent performance index and the seismic energy input to the structural system. This new control law provides feasible control algorithms that can easily be implemented for AMD system and applications to seismic-excited structures. This optimal algorithm is simple and reliable for on-line control operations because control force does not depend on the rigidity of structural system. We investigate the effects of two weighting matrices and a parameter expressing amount of input seismic energy to structure on the control efficieny. This new algorithm has been introduced to a model eight-story building to demonstrate reduction of vibrations caused by medium earthquakes.
