When both a building and its equipment have a vibration controller, an equipment's controller should consider the behavior of abuilding. First control schemes are classified according to the amount of state variables communicated between the controllers and type of control objectives. Then, a high-rise building with an elevator system under seismic excitation is analyzed to compare the performance of the classified schemes that uses the linear quadratic regulator. It is observed that the story drift and the response of elevator rope can be reduced sufficiently even if all the state variables are not communicated.
