Abstract EN
Aiming at the problems of the large torque ripple and unstable suspension performance in traditional direct torque control (DTC) for a bearingless induction motor (BIM), a new method of DTC is proposed based on sliding mode variable structure (SMVS).
The sliding mode switching surface of the torque and flux linkage controller are constructed by torque error and flux error, and the exponential reaching law is used to design the SMVS direct torque controller.
On the basis of the radial suspension force mathematical model of the BIM, a radial suspension force closed-loop control method is proposed by utilizing the inverse system theory and SMVS.
The simulation models of traditional DTC and the new DTC method based on SMVS of the BIM are set up in the MATLAB/Simulink toolbox.
On this basis, the experiments are carried out.
Simulation and experiment results showed that the stable suspension operation of the BIM can be achieved with small torque ripple and flux ripple.
Besides, the dynamic response and suspension performance of the motor are improved by the proposed method.
