Abstract
The edge-end effect in the operation of a Linear Induction Motor (LIM) will lead to great changes in motor parameters, and the d and q axes of LIM have cross-coupling terms. The PI regulator usually used in traditional vector control has a high requirement on the accuracy of parameters, and the PI regulator cannot realize the complete axis decoupling control of d and q, which will lead to the decline of the control accuracy. In this paper, the mathematical model of the LIM considering side effects is adopted, and a complex vector regulator is used to replace the traditional PI regulator, which realizes decoupling control of the d-q axes and eliminates the influence of coupling terms. Finally, this paper is verified on dSPACE semi-physical platform. Results show that the decoupling effect of d-q axes using complex vector regulator is due to the PI regulator.
