In recent years, Along with the fast development of permanent magnet materials, permanent magnet linear synchronous motor（PMLSM） has been get more extensive application. response to the chin and precision movment，have advantages in hig efficient，large export moment，small and easy to control advnatages，has greatly improved the rapid response system into motion precision It has been a new generation of utlra-precision machine tools，most of the technology. Permnaent mgane linear snyehronous motor servo system will be the development of the electrical current and future applications of a linear motor.In this paper，the servo control system of a permanent magnet linear synchronous motor(PMSLM) based on DSP is investigated mostly, give the overall system design program,design a hardware circuit,and the completion of the software part. First of all, through analyzing its interior configuration and movement principle,a mathematical model of PMSLM is established based on space vector of electric current，and on the basis of the rotor flux vector control, space vector PWM waves of velocity loop,
