Ja. Haylock et al., Enhanced current control of high-speed PM machine drives through the use of flux controllers, IEEE IND AP, 35(5), 1999, pp. 1030-1038
This paper compares various types of current controllers, including a novel
method based on flux control. A proportional integral (PI) control method
is used initially, to control the current in a high-speed permanent-magnet
synchronous machine. The performance of this simple PI loop is presented. V
arious improvements to the PI controller are investigated, and the change i
n performance examined. A new current control scheme based on a Aux-linkage
model of the machine is introduced. The performance of the model-based con
trol is demonstrated and compared with the performance of the PI current co
ntroller. Factors affecting the accuracy of the model-based control are giv
en. By incorporating these factors into the model, the performance of the f
lux controller is further enhanced.
