碩士 === 國立交通大學 === 電機與控制工程系所 === 96 === 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.
