Abstract：The traditional control methods which are considered as centralized ones have to measure all signals simultaneously and than the whole control ability of actuator can be calculated and the signals can be sent out for vibration control. These methods have complex control system and poor reliability. In recent years, the decentralized control strategy based on the feedback of partial state has simple design and high reliability, and it has become the hot hit of resent research. Nowadays, the control ability of actuator is controlled just by using the measured signal of a building’s two interfacing floors. Although it can control the response of structure, the information is too less and the control performance is not good yet. As a result, basing on the robust control strategy and by setting up special matrix, a robust decentralized control method based on the measured signal of a building’s four interfacing floors has been proposed. And from the performance of dynamical simulation, the control performance of proposed method is much better than the one which depend on the signal of two interfacing floors at the same control ability.
