Abstract
Thrust ripples in Permanent Magnet Linear Motor(PMLSM) are mainly generated by cogging force. Cogging force caused by the interaction between the iron core and the Permanent Magnet(PM), and end effect. This paper has proposed a control method for thrust ripples suppression and design of one-chip proceeding digital controller using TMS320LF2407. This control method is realized by Field Oriented Control(FOC) adding to current compensation. The effectiveness of proposed control method is verified by experimentation comparing between the compensation and non-compensation.
