摘要: 针对传统的永磁直线同步电动机驱动的垂直提升系统容易产生失步和振荡现象的问题,提出了一种永磁直线同步电动机速度、电流、位置闭环矢量控制系统的设计方案,采用次级磁链定向的矢量控制技术,结合空间电压矢量脉宽调制方法,在Matlab/Simulink环境下对垂直提升系统的分段式永磁直线同步电动机闭环矢量控制系统进行了建模与仿真,并基于实验室自制样机做了闭环实验。实验结果表明,该系统具有良好的动、静态性能,基本满足垂直提升系统相应性能的要求。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.
