應用動態模糊系統於旋轉式倒單擺系統之分析與控制 周晏鈴、陳昭雄

E-mail: [email protected]

摘 要

倒單擺系統為典型的非線性不穩定系統,常被應用於驗證控制理論可行性之實驗設備。 本文提出一動態結構模糊系統,用 於解決非線性不確定系統之參考模式適應控制問題。而動態模糊系統主要是重建未知非線性動態系統。在動態結構系統中

,參考模型提供閉回路性能回饋產生或修正一個模糊近似資料庫。模糊規則數基於所需的準確度可以隨著時間增加或減少

。透過結合動態結構模糊系統和里阿普諾夫的穩定法則,所獲得之適應控制法則使追隨誤差收斂至所需的準確度。 最後,

我們模擬一倒單擺系統之控制,來驗證本文所提方法之有效性。

關鍵詞 : 模糊控制 ; 非線性不確定系統 ; 適應控制
