“…11 and 12 show that, in the case of r s included in all equations, the flux current component (i sx ) and rotor flux (ψ r ) values are smaller than without r s taken into account. Thus, with the same load torque, the torque current component (i sy ) in the case with r s should be bigger than without r s case, according to (8).…”

“…However, the 1990s showed renewed interest in the optimal methods for the FW control of IMs [5][6][7]. For rotor-flux orientation it was shown that the classical FW method of selecting the flux-producing current component proportional to the rotor speed inverse, yields too large current value, and a maximum torque is not achieved [7,8]. Various strategies for improved FW operation were proposed [9][10][11].…”

Abstract. In this paper, an analysis of the influence of the stator winding resistance on the field-weakening operation of the induction motor drive based on the Direct Rotor Flux Oriented Control (DRFOC) is presented. Two scenarions of the optimal field-weakening algorithm (with and without stator winding resistance taken into account) have been compared and verified through simulation and experiment, under different operation conditions of the DRFOC drive system with 3 [kW] induction motor.

“…When the induction motor is running, in order to reach the requirement of high speed, the induction motor is affected by the supply voltage, and the current will also be influenced by the factors of the motor and the inverter. When the motor runs with load, its output torque The requirements will be relatively high, usually using some speed control method [1] , this time is in the vector control method by reducing the flux, that is, the field weakening speed to make the motor voltage and current are subject to power supply and inverter limits In the case of high-speed output and torque stable output, although the re-vector control method is easy to achieve speed control, but how to make it still under load with a stable output is more difficult [2] .…”

Abstract-As for the induction motor with load needs to run in a large area, so speed regulation is an essential part of the current at a higher speed to prevent the voltage and current exceeds the rated value of the normal operation of the motor damage to the need for reasonable distribution, That is, the motor into the weak magnetic area in order to achieve the motor speed. Under the rotor flux orientation control, the current closed-loop control algorithm is realized based on the traditional 1 / wr flux-weakening control, and the algorithm is implemented in MATLAB. Meanwhile, the pid Parameter tuning, the results also show the effectiveness of the algorithm.

“…Thus, its torque generating capability can not be maximized under the given limits; and (3) the effects of parameter variations on the field-weakening control and field-orientation control are not considered. To improve the performance of 1/ω r approach, in the control approach presented in [3], the optimal current commands and the changed base speed are determined to yield maximum torque per ampere over whole fieldweakening speed range. There were still another approaches [4,5] being emphasized in determining the suitable flux level based on stator flux-oriented control.…”

The field-weakening control of an indirect field-oriented (IFO) induction motor (IM) drive with good dynamic and static performances is studied. First, the operating characteristics of an IFO induction motor drive under conventional field-weakening control are studied to comprehend its limitations. In the proposed field-weakening control scheme, the normal d-axis flux current command is the first set. It consists of a major component generated based on conventional 1 /ωr approach and a loading compensating component. Then the normal command is augmented with transient and static compensating components to automatically further improve its defects. During the transient period, the former component is generated from the torque current tracking error and added to adaptively further adjust the field such that the current tracking control performance is improved; hence, the transient torque generating capability is also enhanced accordingly. Finally, a robust current controller and a detuning compensator are developed to enhance the current tracking performance of a detuned induction motor. As the transient is elapsed and enters the static period, the static compensating flux current command is tuned using the proposed intuitive approach to let the motor quickly reach a stable condition having better static torque generating capability, thus the energy conversion efficiency is improved. Effectiveness of the proposed field-weakening control method is demonstrated experimentally.
