复合矢量控制中的定向校正

Correction of Orientation in Compound Vector Control

本文首先讨论磁链开环控制系统中的走向偏差，然后分析复合矢量控制系统如何通过校正来消除定向偏差，达到正确的磁场走向控制。采用复合矢量控制原理的交-交变频调速装置已成功地应用于轧机主传动。文中还介绍了试验和现场的测试结果。

In this article the orientation deviation in open-loop control system for magnetic flux is first discussed,then the eliminating of the orientation deviation in compound vector control system is analysed,in which correct orientation control of magnetic field is obtained through correction.The cycloconverter-fed variable speed drives using compound vector control principle have been successfully put into operation for mill main drives. In addition,the measureddata in the test and field are introduced.
