由於建築結構系統質量大，主動控制的能量需求很大，本研究使用慣質元件取代質量塊，透過將直線運動轉變為旋轉運動能量轉換達到質量放大的效果，大幅降低傳統質量阻尼器質量塊體積與質量的需求，此新型的主動控制元件稱為主動慣質阻尼器。本研究以控制理論設計主動慣質阻尼器的兩種力量控制架構，實驗結果顯示，結合位移回饋與力量控制之控制方法，除了有效提升主動慣質阻尼器的力量追蹤控制性能並降低摩擦力的影響之外，更可減少致動器在結構受震後的永久位移量。
地震模擬振動台常作為地震工程研究之實驗驗證工具，然而振動台實驗試體造價昂貴且實驗常不具可重複性，因此本研究中以即時複合實驗進行含主動慣質阻尼系統結構之耐震性能評估，將含主動慣質阻尼之十層樓結構拆解為數值模型與測試元件，其中十層樓結構為數值模型，主動慣質阻尼器為測試元件。本研究使用啟發式演算法進行結構控制律的最佳化，數值模型受到地震擾動後，透過結構控制律即時算出控制力，藉由安裝於實驗室之主動慣質阻尼器施加控制力後，將量測到的力量傳回數值模型，以完成即時複合實驗。實驗結果顯示，啟發式演算法最佳化之控制律較傳統能量法之控制律具有較好之耐震性能。此外，即時複合實驗可有效地應用於主動慣質阻尼結構系統之耐震性能評估，大幅地降低結構試體製作之成本與時間。
最後，由於即時複合實驗無法得到主動慣質阻尼器與結構互制對力量控制性能之影響，本研究中以振動臺試驗進行含主動慣質阻尼系統之性能測試，藉以了解真實情況之力量追蹤控制性能。實驗結果顯示，主動慣質阻尼系統除了有效地降低結構加速度反應，更在力量追蹤控制擁有良好的性能。

In this study, a novel active control device has been proposed, designed, and fabricated. This device is composed of a hydraulic actuator, and an inerter, namely active inerter damper (AID) which incorporates the characteristics of inerter into active control system. The AID has a special property that the force generated is proportional to the relative acceleration between the two ends of the inerter. By converting linear motion to rotational motion, the equivalent mass can be amplified significantly. Therefore, the inerter has smaller mass and volume than the conventional mass damper. Two force tracking control methods for AID have been proposed, synthesized and validated. The results show that the combination of displacement feedback and force control improves the force tracking control performance effectively and suppress the friction effect. Meanwhile, the displacement of actuator is able to re-center after excitation.
Shake table testing has been considered as one of the most effective methods to investigate dynamic responses of buildings subjected to ground motions for earthquake engineering studies. However, shake table testing is not repeatable as long as specimens become inelastic. Therefore, real-time hybrid simulation (RTHS) has been adopted to evaluate the seismic control performance of an AID system. A 10-story shear building with an AID installed at the roof was utilized as a benchmark. The AID was physically tested while the shear building was numerical simulated. Metaheuristic optimization was applied to optimize the linear-quadratic regulator (LQR) for structural control. When the shear building was subjected to ground motion, the control force was calculated from LQR and treated as the desired force to be tracked by the AID. The achieved force of AID was measured and fed back to the numerical model until the entire RTHS ended. The results show that seismic response of the structure was mitigated effectively.
In order to verify the effect of control-structure interaction (CSI) on the force tracking control of AID, shake table testing has been conducted. Experimental results demonstrate that the force tracking performance of the proposed control methods remained exceptional considering the CSI. In addition, the acceleration response of the specimen was effectively reduced.
