Abstract
Recently, base isolation control of buildings has been devised to raise safety and comfort for the great earthquake. The Sliding Mode Control (SMC) theory which is one of nonliear control theory is applied to a semi-active base isolation control in this study. The advantage of the SMC method is the simplicity of design methodology and the robustness of control low. However it is important to use the disturbance information to obtain high performance. The purpose of this study is to propose the Disturbance-Accommodating Sliding Mode Control (DA-SMC). In this method the switched hyperplane is designed by augmenting the state space to that including the disturbance dyanamics. This study deals with the control problem of a ten-degree-of-freedom structural model with semi-active base isolation. In order to investigate the performance of the proposed method, computer simulation was caried out, and as a result, the effectiveness of the method was shown.
