The wound induction motor can provide high starting torque and reduced starting current simultaneously by inserting large scale resistor. And this technique is one of the well known methods among the induction motor starting methods and generally used for heavy load starting such as Crain and Cement factories The conventional PI controller has been widely used in industrial application due to the simple control algorithm and in general, PI controller is used for control of current, torque, position, and speed for the wound induction motor drive system. However, the system may result in poor performance since sensors have to be used, which in turn is limited by the environmental condition
Recently, to overcome these problems, many sensorless vector control methods for the wound induction motor have been studied This paper presents MRAS method with on-line stator resistance tuning for sensorless vector control of the wound induction motor drive. In conventional MRAS method, in low frequency, stator resistance variation can result in poor performance Therefore, to overcome several shortages of the conventional MRAS caused by parameter variation and enhance robustness of the sensorless vector control, this paper investigates a MRAS method with on-line stator resistance tuning for sensorless vector control of the wound induction motor.
The validity and effectiveness of the proposed method is verified through digital simulation.
