Paper Title:
Direct Slip Linear Control of Bearingless Induction Motor Based on Space Vector Modulation
  Abstract

Due to the complex nonlinear coupling characteristics of non-bearing induction motor control system, the basic requirements to maintain the stable operation of the bearingless induction motor is to achieve the decoupling control between electromagnetic torque and radial force, and it is also difficult to design efficient and reliable control system in this field. In this paper, the entire control system is divided into the rotating control system and suspension control system, a control method direct slip linear control based on space vector modulation (DSLC-SVM) is put forward. As to rotating part, because of the direct control of the slip, the flux magnitude deviation and the current total harmonic distortion (THD) can be reduced. As to suspension part, the voltage PWM controlled inverter is adopted to improve the utilization of DC bus voltage and reduce the impact of high harmonics. At last, by comparing the simulation results with traditional control methods, the feasibility and correctness of this method are demonstrated.
