Research for the Control System of a Pulsed Power Permanent Linear Synchronous Motor

Abstract

Pulsed power linear motor is the basic power device in electromagnetic launching (EML) technology. When this technology combines with permanent magnetic linear synchronous motor (PMLSM), a pulsed power permanent magnet linear synchronous motor (PP-PMLSM) is generated. In this paper, the analysis of cogging force and thrust characteristic of this type of motor are presented, and the scheme comparison of bilateral magnet arranged by N face S with N face N direction is made, at last, the digital control system of the PP-PMLSM is designed and realized. The system design is simple, and it improves the control effect.
