Working Principle

Bearingless induction motor is a multi-variable, nonlinear and strong coupled system. On the basis of working principle of bearingless induction motor, independent control of suspension control windings is combined with rotor flux-oriented control of torque control windings in the paper. Meanwhile, in order to improve robustness and decoupling performance of system, the modified internal model control (MIMC) is applied in the control of two sets of windings to realize the dynamic decoupling of currents and stable control of radial displacement. The results of simulation experiments show that the proposed strategy has good ability of disturbance rejection and robustness, so the stable operation of motor can be achieved effectively.

Vector Control System

As a high-performance variable frequency control technology, vector control has been widely used in the field of AC speed regulation. However, the cross-coupling potential of the induction motor after the vector transformation still affects the system performance. Therefore, the method is studied in which stator current is decoupled to excitation component and torque component using internal model control, and the internal model decoupling stator current controller is designed based on rotor field orientation. The simulation model of induction motor vector control system based on internal model decoupling is constructed with Matlab/Simulink. The simulation result shows that the internal model controller is superior to the traditional PI controller in disturbance-rejection performance and robustness.

Model Control

The bearingless induction motor is a nonlinear, multi-variable and strongly coupling system. In this paper, a new nonlinear internal model control (IMC) strategy based on inverse system theory is proposed to realize the decoupling control for the bearingless induction motor. The mathematical model of the motor is built and then the inverse system method is applied to decouple the original nonlinear system. Finally the internal model control method is introduced to ensure the robustness of the closed-loop system. The effectiveness of the proposed strategy are demonstrated by simulation.
