主動式大樓減震系統之控制研究

本研究之主要目的是將主動式大樓減震系統利用強健之適應性控制，使大樓能夠快速的達到定位不再搖晃，其主要的減震機構為利用慣性輪旋轉進而藉由轉動慣量產生平衡力使得當大樓在受到地震之震動時能有效的減低其震動以減低對建築結構所造成的傷害。由於大樓之重量不斷的變化以及隨著時間材料的劣化，系統參數將大幅度的改變。若採用傳統的控制方法將無法有效的應付其多變的環境因素所造成的不穩定現象。在本研究當中，則以一個二階的動態模型來代表整個平台模組的動態反應。當非線性適應性控制法則設計完成之後，利用上述推導出來動態模型來驗證控制法則的性能。結果顯示，所設計的控制法則能夠成功的控制大樓的搖晃角度以及平台的位移量，並提高其實用性與可靠性。

The aim of this research is to study on the control of vibration suppression for building. Vibration suppression is controlled using a rotation reaction wheel produces a balance force (owing to inertia) when the building suddenly quakes. Because the building weight changes and material deteriorates, the parameters of the system may change significantly. Traditional controls cannot effectively deal with changing environmental factors, and they may cause instability of the system. In order to overcome parameter uncertainty, an adaptive version of the developed nonlinear controller is also presented. The control algorithms as well as the convergence analysis are based on the Lyapunov theory and Barbalat’s lemma. To demonstrate the validity of the controller, the performance of the control law is verified by real-time experiments and simulations.
