유도전동기 벡터제어에서 퍼지제어기에 의한 시정수 보상 = Compensation of the Rotor Time Constant using Fuzzy Controller in Induction Motor Vector Control

다국어 초록 (Multilingual Abstract)

The vector control system of an induction motor is the high performance drive system to achieve the instantaneous torque control. The vector control system is greatly divided into the direct control, and the indirect control that the most widely is used, The indirect vector control needs the rotor time constant, which changes widely according to the temperature, frequency, and current amplitude, The incorrect time constant leads to the saturation of magnetic flux or under-excitation phenomena, As a result, that deteriorate the control performance<br/>
Therefore, in this paper, the effect of time constant variation is investigated and its on- line tuning algorithm is proposed The time constant using the torque angles was calculated and that of the validity of algorithm proposed was proved through the computer simulation and the experiment
