    Abstract: 隨著科技的發展和社會的進步,電梯的需求量越來越多。此外,由於高速電梯和超高速的電梯的迅速發展,人們的要求不僅僅只是在電梯的速度。除了電梯的速度和性能之外,人們的需求的焦點也逐漸轉移到電梯的舒適度。發展不僅僅快而且又要舒適的電梯成為生產電梯業界的主要課題。 智慧型電梯控制器設計的方法主要是根據參考模型適應性控制(model reference adaptive control)。其中控制器包括有適應性前饋控制器、適應性回饋控制器和輔助訊號。適應性前饋控制器的部分設計成電梯系統的逆轉系統,當我們確切知道電梯系統的參數時,我們的規劃的命令和輸出命令的誤差時將會等於零。 適應性回饋控制器的部分設計成傳統的PID控制,適應性回饋控制器的設計可以增加閉回路控制的穩定性。而輔助信號則是設計來克服電梯系統運轉時所產生的庫侖摩擦力。根據這個控制法則去控制電梯並不需要知道電梯系統的參數。這個智慧型電梯控制器可以自動調整包含回饋控制PID增益值及前饋控制之質量 、阻尼 、及摩擦力 。智慧型電梯控制器可以不需要瞭解確實的電梯參數。所以,這個智慧型控制器可以適用在不同參數的電梯控制上。 The objective of this thesis is to develop an intelligent elevator controller. The intelligent controller could be used in all elevator system. The approach of the designed intelligent controller is based on the model reference adaptive control. The controller includes an adaptive feedforward controller, an adaptive feedback controller and an auxiliary signal. The proposed control algorithm is presented in this thesis, does not require the exact dynamic model of the elevator system. The intelligent elevator controller automatically tunes two kinds of parameters, one belongs to the feedback control that are PID gains and the other belongs to the feedforward control that are mass, damping and friction. Furthermore, adaptive law, which is a simple algorithm, generates the control gains and the updated time is shortly. Therefore, the proposed scheme is suitable for controlling elevator on-line with high sampling time.
