碩士 === 國立成功大學 === 土木工程學系 === 105 === The performance of the Leverage-type Stiffness Controlled Mass Damper (LSCMD) had been verified in single-degree-of-freedom experiments. In order to apply Least Energy Method (LEM) control law to LSCMD with a multiple-degree-of-freedom,simulation results are given in this study. However, the computation of control command requires full-state signals feedback, it must to be face many difficult obstacle. To resolve this problem, the simplified numerical model which is utilized to easily compute this control law is proposed in this study. In addition, the performance comparison of the first generation LSCMD(LSCMD I) system whose equivalent damping ratio is high and the second generation LSCMD(LSCMD II) system also proposed. To verify the feasibility of the LSCMD system whose control force is computed based on the simplified numerical model, real time hybrid testing for the LSCMD I and the LSCMD II is conducted.
