Simulation of Vertical Hoisting System Driven by PMLSM and Its Implementatio

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.
