摘要
提出了采用磁场定向控制一理论来改善矢量控制的教学。在异步电机统一的数学模型的基础上 ,构造磁场定向控制统一理论 ,通过对其中转子定子折算系数的不同取值 ,分别方便地推导出转子磁场定向控制、定子磁场定向控制和气隙磁场定向控制。通过对三种磁场定向控制的比较 ,加深了对矢量控制的认识。采用基于 Power Point的多媒体教学实践证明了本文提出的教学改革方法的有效性。
In this paper, the University Field Orientation(UFO) control theory is used to improve the teaching quality of vector control section. On the basis of the unified mathematics model of Im motors, the UFO control theory is deduced. The controller of rotor field orientation, stator field orientation and air gap field orientation can be easily derived through the difference rotor/stator convert coefficient in UFO controller. With the comparison the three difference field orientation controlles, the understanding to the vector control theory can be strengthened. The validity of teaching reform method proposed in this paper is proved by the teaching practice with the aid of PowerPoint multimedia.
