本論文的目的在研究步進馬達精密控制轉子角度的方法，並研究馬達負載影響下驅動角度的變化，利用非線性補償降低轉子角度與理論角度的誤差。;The purpose of this paper is to research the precise control method of the stepping motor rotor angle, and research the influences in the motor driver angle under different load. Use the non-linear compensation to reduce the error between rotor angle and theoretical angle.
