本文主要目的是進行三相直流無刷馬達的數學建模,必須先了解馬達的組成部分以及驅動的方式,以微分方程式的形式呈現,最後採用並用MATLAB/SIMULINK進行模擬驗證馬達的響應行為。 This thesis focuses on the mathematical modeling of 3 phase brushless DC motor. The integration components of motor and electrical drives must be understood and represented by a series of differential equation. Matlab/Simulink is adopted to build block-wise model of motor behavior and run to simulate the associated dynamical response.
