Abstract

Analysis and contrast between air-gap flux orientation and rotor flux orientation of bearingless induction motor are be given firstly, at the same time, the flux orientation control strategy and induction compensation method of magnetic suspension system are analyzed. Then, according to the operation characteristics of bearingless induction motor, the combined control strategy is selected, i.e., rotor flux orientation strategy will be adopted for four-pole torque system and air-gap flux orientation and induction compensation control strategy will be adopted for two-pole magnetic suspension system, and the simulation and experiment of decouple control system of three-phase bearingless induction motor have been made. The simulation and experiment results have proved the validation of the united control strategy.
