Abstract

The application of the 3 phase induction motor is increasingly developing, this has led to research on speed regulation of 3 phase induction motors is also growing, because the use in industry and especially in hybrid vehicles is increasingly being developed. However, there are several disadvantages of an induction motor, one of which is the non-linear parameter characteristics, especially the rotor resistance, which varies in value for different operating conditions, so that it cannot maintain its speed constantly when a load changes. Therefore, to get constant speed and better system performance against load changes, a controller is needed. This study aims to implement the vector control method in the 3 phase induction motor speed control application in following the reference speed. In vector modeling, the 3 phase parameters (ia, ib and ic) will be transformed into direct quadrature (dq) parameters where in this parameter the setting of the field size and torque can be adjusted separately. In the implementation results, it can be seen that the use of vector control can be used as an approach in regulating the speed of an induction motor.

Highlights

  • Aplikasi motor induksi 3 fasa semakin lama semakin berkembang, dikarenakan kehandalannya pada penggunaan di industri dan khususnya pada kendaraan hybrid semakin banyak dikembangkan.Namun ada beberapa kelemahan motor induksi yang salah satunya adalah karakteristik parameter yang tidak linier, terutama resistansi rotor yang memiliki nilai yang bervariasi untuk kondisi operasi yang berbeda, sehingga tidak dapat mempertahankan kecepatannya secara konstan bila terjadi perubahan beban

Summary

PENDAHULUAN

Aplikasi motor induksi 3 fasa semakin lama semakin berkembang, dikarenakan kehandalannya pada penggunaan di industri dan khususnya pada kendaraan hybrid semakin banyak dikembangkan.Namun ada beberapa kelemahan motor induksi yang salah satunya adalah karakteristik parameter yang tidak linier, terutama resistansi rotor yang memiliki nilai yang bervariasi untuk kondisi operasi yang berbeda, sehingga tidak dapat mempertahankan kecepatannya secara konstan bila terjadi perubahan beban. Dikarenakan hal tersebut, untuk mendapatkan kecepatan yang konstan dan performa sistem yang lebih baik terhadap perubahan beban dibutuhkan sebuah pengendali
