中文摘要 | 本文主旨為驗證滑動模式控制法(以下簡稱SMC法)應用於主動式樓房結構控制實驗,實驗部分在國家地震工程研究中心進行實尺寸之三層樓鋼結構振動台試驗,試驗之目的為使結構物在受地震力時能確保安全與穩定。並利用數值模擬SMC法之動態行為,與結構控制之實驗相互比較。 實驗結果顯示,實驗的控制可達預期效果。但因實驗中可能產生不可預期的因素較多,數值模擬之控制效果會比較好。但證明了SMC法應用在主動控制實驗上,確實能夠達到快速響應、控制算程計算簡單及對系統參數變化和外部干擾的低靈敏度等優點O 依數值模擬之結果,若改用模糊滑動模式控制法(以下簡稱FSMC法)做為控制律時,我們發現FSMC1法比SMC法之控制效果更佳,因FSMC法比SMC法更接近於人類思考模式、控制程序使用專家知識與語言規則庫,讓使用者更容易了解與應用,而且FSMC所需要之控制力比SMC要來得小,更能符合實際需求,控 |
英文摘要 | The purpose of this research is to develop two robust active structural controls for a building structure. Itis desired that the structure under control can be sustained in safety and stability when subjected to earthquake force. Comparing the result of experiment. The results of experiment indicate that the control is effective. But experimental error is more than simulation. So the result of the simulation is better than experiment. Itshows that SMC can be applied to active control experiment, and it also has some advantages: Low sensitivity of dîsturbance. Simple computation of control algorithm. According to the results of experiment, it is shown that the dynamic responses of a building structure can be reduced by the fuzzy sliding mode control (FSMC) and the VSC. HoweVer, the control force of FSMC is smaller than that of SMC, and effectiveness of FSMC is better than that of SMC. So, the FSMC method is a better one can obtain an objective to a building structure. |
