包装行业中的变频器矢量控制技术

Vector-control on Variable-frequency Converter in Packing Trade

为了更好地解决包装行业中电力拖动设备的机械性能和调速问题,选用了矢量控制型变频器.介绍了变频器矢量控制的基本原理,并且建立了异步电动机在不同坐标系下的数学模型.最后采用磁场定向控制方法,导出了异步电动机的矢量控制数学模型,方便了变频器矢量控制的实现.图1,参4.

In order to solve perfectly mechanical performance and varying - speed problem of the Electrical - drive equipment in packing trade, the technology of vector control is applied to variable - frequency converter. In this paper, the basic principle of vector - control are introduced, and the mathematical models in different reference frame of asynchronous motor are established. Finally, using the magnetic field - oriented control method, the vector - control mathematical model of asynchronous motor was derived. Convenience to the vector control realization of the frequency changer was provided. 1fig. ,4refs.
