Servo control system for permanent magnet linear synchronous motor based on hall-element

In this paper, we mainly research control technology for permanent magnet linear synchronous motor (PMLSM) based on hall-element, which is a part of free piston generator used in hybrid vehicles, adopt vector control method in which d-axis current of stator is set to be zero, combined with SVPWM and construct software and hardware platform of the control system, based on which we do some relevant tests without load.
