“…In the oriented flux vector control system of the bearingless induction motor powered by the inverter [11][12][13][14], when the BIM works below the rated speed, the motor flux can be kept constant, and its maximum output torque [15][16][17] is only limited by the rated current and the maximum current of the inverter; when the motor speed exceeds the rated speed, it enters the field-weakening region. With the increase of the counter electromotive force of the rotor winding, the output voltage of the inverter will be limited, which affects the maximum torque output of the motor.…”

In order to realize the maximum torque output (MTO) in the field-weakening region for a bearingless induction motor (BIM) stator vector control, a flux feedforward control strategy is proposed. Firstly, based on the restrictions of the stator flux oriented control and the dynamic characteristics of the current in the BIM field-weakening region, the optimal distribution of the torque current and excitation current and the dynamic model of the maximum torque output strategy are analyzed. Then, the fieldweakening region could be divided into two parts according to the change of slip. It can be proved that the BIM works under the voltage and current limitations in the field-weakening region I, and works under the voltage and torque limitations in the field-weakening region II. By this way, the optimal flux mathematical model of the BIM can be obtained. Finally, the MTO in the field-weakening region is proved. The simulation and experiment results show that the proposed flux feedforward control strategy in the field-weakening region can make the output torque and current tracking effect improve significantly when the BIM runs beyond the rated speed. At the same time, the good suspension performance of the BIM is realized.

“…The second direction of research is the impact on control software, proposed FW algorithms to improve the speed's range. Based on the classification of the study [13], there are four main methods in PMSM velocity regulation in FW area: TFLUT test [14]- [16], direct current calculation (DCC) [17]-[19], vector current control (VCC) [20]- [22] và flux vector control (FVC) [23]- [25]. Bolognani et al [26] gave some comparisons between these control algorithms.…”

This paper proposes an advanced flux-weakening control method to enlarge the speed range of interior permanent magnet synchronous motor (IPMSM). In the deep flux weakening (FW) region, the flux linkage decreases as the motor speed increases, increasing instability. Classic control methods will be unstable when operating in this area when changing load torque or reference speed is required. The paper proposes a hybrid control method to eliminate instability caused by voltage limit violation and improve the reference velocity-tracking efficiency when combining two classic control methods. Besides, the effective zone of IPMSM in the FW is analyzed and applied to enhance stability and efficiency following reference velocity. Simulation results demonstrate the strength and effectiveness of the proposed method.
