直流有刷馬達之系統判別

Abstract

本篇論文研究的主題在利用最小平方估測法，有效率的找出直流有刷馬達的最佳轉移函數，以便我們在設計馬達系統的控制器時，盡可能達到簡化量測過程且不失準確的效果。文中經由架設之實驗儀器，實際量測直流有刷馬達(SANYO DENKI U718T-012EL8)的轉移函數，並和本研究利用最小平方估測法所求得之轉移函數做分析比較，以驗證本文方法的可行性並探討其優缺點。

The purpose of this thesis is to utilize the least-square estimation method to find out the optimal transfer function of a brush DC motor system efficiently. So that we can simplify the measure process without losing the accurate result as much as possible while designing the controller of the motor system. We actually measure the transfer function of the brush DC motor system (SANYO DENKI U718T-012EL8) via laboratory apparatus, and compare with the transfer function from the least-square estimation method. Finally, we can verify the feasibility of the method in this article and discuss its advantages and disadvantages.
