為了設計或分析一個系統,通常必須先了解該系統的動態結構特性。但對一個耦合的結構來說,實際系統的模擬是非常困難的一件事。在本篇論文中,針對多輸入多輸出的結構進行解耦合,採用直接消除多訊號間的相互影響關係,從而得到多個單輸入單輸出結構狀態模型,並採用實驗驗證有限元素法軟體的準確性。最後,使用有限元素模型及引用白色干擾的觀念,討論在上述解耦合過程中的限制性。
In order to design a suitable controller or analyze a system, we must understand the dynamic characteristics if we want to get the best performance. But sometimes the real coupled MIMO model is difficult to be found because input and output signals are interactive. In this thesis we concern to analyze and evaluate the estimation accuracy of decoupled MIMO model. From experimental results, we will evaluate the accuracy of FEMLAB. Then we use FEMLAB to evaluate the restrictions of the decoupled MIMO model and also use white noise testing to justify its adaptation.
