中文摘要 |
基於李亞普諾夫理論(Lyapunov Theorem) ,本論文為解決強韌追蹤問題,提出一個具有擾動估測器之參考模式調適可變結構控制器(MRAVSC)。 此控制器設計方法乃是針對任意相對級數並且在輸入端及輸出端含有相加性與相乘性的未模式化不確定量之多輸入多輸出線性非時變系統。 藉著上述控制器中所隱含的擾動估測器,擾動與追蹤誤差的微分皆可被估測。 再者,此控制器同時具有調適控制機制,此乃是用來調適擾動估測誤差的未知上界。 本控制器可保證閉迴路系統的uniformly ultimate boundedness特性。 最後,針對本論文所提出的控制器設計法則,以二個數值範例來展示其可行性。 |
Abstract |
Based on the Lyapunov stability theorem, a model reference adaptive variable structure control (MRAVSC) scheme with perturbation estimation is presented in this thesis for solving robust tracking problems. The plant considered belongs to a class of MIMO linear time invariant systems with arbitrary relative degree possessing additive and multiplicative unstructured uncertainties in the input and output channels. By introducing a perturbation estimation process embedded in the proposed control scheme, both the perturbations and differentials of tracking errors can be estimated. In addition, the proposed control scheme also contains an adaptive mechanism in order to automatically adapt the unknown upper bound of perturbation estimation error, and guarantee the property of uniformly ultimate boundedness for the closed-loop controlled system. Finally, two numerical examples are presented to demonstrate the feasibility of the proposed control scheme. |
