Spice 上電梯昇降系統之設計

Abstract

在這篇論文中提出了一個能在~Spice~模擬器上建立電機$-$機械系統模組 化等效電路模型的一般法則。根據此法則我們將電機$-$機械裝置的機械 特性轉換成以電氣形式表示的等效電路模型，使其能在~Spice~上進行電 路模擬。我們建立了交、直流馬達和功率轉換器 (PWM)等的等效電路組立 模型(Macro Model)，根據模擬和實驗的結果，驗證了這些模型的正確性 與實用性。並以三相感應馬達作為電梯昇降系統的主機驅動馬達，應用向 量控制理論建立一個可以完全在~Spice~上進行設計與模擬的交流電梯伺 服系統，經由實驗模擬的結果顯示出我們所設計電梯伺服控制系統具有良 好的速度穩定姓及精確的電梯行程控制。 In this thesis,we propose a general procedure for developing Spice macro models of electrical$-$mechanical systems. We also employ these models in designing an elevator system. The details of the design of the general elevators are reviewed in this thesis. Several DC and AC motors have been equivalently transformed to macro$-$circuits which simulate both the electrical and mechanical characteristics of the motors. The vector$-$control theorems are employed in designing the elevator system which includes a three$-$phase induction motor, a PWM driving power inverter, a coordinate$-$transformation function, and the associated controllers. The design steps for this system, including the steps to simplify the induction motor model by using the coordinate transformation are showen inside. The~Spice~experiment results have showen good performance for the speed profile control of the elevator system designed here.
