无轴承异步电机是一个强耦合的非线性复杂系统，实现其电磁转矩和径向悬浮力之间的解耦控制是该电机稳定运行的前提。本文在研究电机磁悬浮机理的基础上，提出了利用气隙磁场定向控制来实现两者之间的动态解耦控制。仿真实验也证明该控制算法不仅能实现电机稳定的悬浮，而且使电机具有良好的调速性能。 

The bearingless induction motor, which combines the induction motor and magnetic bearing is a strongly coupled complicated nonlinear system; the decoupling control of the electromagnet torque and radial levitation force is the base of the stable operation of the bearingless motor. In this paper, the airgap motor flux oriented vector control is proposed to realize the decoupling control of this nonlinear system even in the transient case based on the levitation principle. Simulations show the stable suspension and good performance of the proposed algorithm.
