Abstract: In view of the problem that traditional vertical hoisting system driven by PMLSM is easy to produce phenomenon of out of step and oscillation, the paper proposed a design scheme of closed-loop vector control system of PMLSM with speed, current and position. It made modeling and simulation for the closed-loop vector control system of PMLSM with segmentation structure of vertical hoisting system under Matlab/Simulink by using vector control technology of oriented secondary flux and SVPWM method, and made closed-loop experiment based on self-made prototype in laboratory. The experiment result showed that the system has good dynamic and static performances and basically meets with demands of vertical hoisting system.
