However, larger stroke is required for better performance. To resolve this problem, leverage-type stiffness controllable mass damper (LSCMD), a semi-active mass damper, is proposed in this study. By adopting the fuzzy control rule (FCR), the control performance of the LSCMD is compared with the linear quadratic regulator (LQR) and the least energy method (LEM) rules. Different semi-active control rules will drive the pivot position of the lever-arm of the LSCMD and be able to control the damper stiffness and restoring force in real-time. On the stroke suppression performance, FCR is better than LQR. Moreover, FCR and LEM have similar control performance on displacement suppression at the isolated floor. The simulation results showed that the FCR has very good control results and it does not need to identify the precise parameters of system. Finally, the experimental verification of its applicability is conducted by a series of shak-ing table tests. Shih-Yu Chu 朱世禹 2015 學位論文 ; thesis 208 zh-TW |
