Pemodelan Direct Field Oriented Control (D Foc Pada Pengaturan Kecepatan Motor Induksi Tiga Phasa

Abstract

The 3 phase induction motor in its use is increasingly growing, so research on the speed regulation of the 3 phase induction motor is also increasingly being studied. This is because the use of 3 phase induction motors in industry and especially hybrid vehicles is increasingly being developed. But there are some disadvantages of induction motors, one of which is the characteristics of non-linear parameters, especially rotor resistance which has varying values for different operating conditions, so it cannot maintain its speed constantly if there is a change in load. This of course can affect the performance of an induction motor. To get a constant speed and better system performance on load changes a controller / controller is needed. This study aims to model the parameters used in Direct Field Oriented Control (DFOC) using Matlab SIMULINK. With the controlled dq parameter, the induction motor will be more stable, because the dq parameter determines the stability of the changes in torque and flux in the induction motor. In the results of implementation, it can be seen that the use of DFOC can be used as an approach in the speed regulation of the induction motor. and with the use of PI controls it can help the output response get better with a shorter response time to reach the reference value.

Design And Simulation Of 10 kW BLDC Motor Speed Control For Electric Vehicles Using FOC Based On Fuzzy Logic Control

“…Due to the absence of friction, BLDC motors have another advantage in the form of lower maintenance costs than conventional DC motors because there are no components that wear out due to friction. The basic components of a BLDC motor include a rotor with permanent magnets, a stator with 3, 4 or more phase windings, a rotor position sensor, and an electronic circuit to regulate the phase of the stator winding [12]. BLDC motors use a control circuit to replace the function of the commutator by supplying coil energy to the stator in a sequence of commutation steps.…”

“…Research on field oriented control has been carried out for a long time, some of its application is to regulate the speed of induction motors, as was done in [11] in [12]. In [12] research was carried out to examine the speed control of a three-phase induction motor which applied FOC control on a PID control basis.…”

This research method was carried out by simulating the Self Tuning Regulator adaptive PID control model that had been created and then realizing the control model using the AVR Atmega16 Microcontroller.…”

Perancangan Generator Axial Fluks 3 Phasa Pada Pembangkit Listrik Tenaga Ombak (PLTO)

“…Tipe dari motor industri berdasarkan pada jenis rotor dibagi menjadi dua macam yaitu wound rotor (tipe motor yang memiliki rotor terbuat dari lilitan) dan squirre-cage rotor yaitu kondustri rotor disusun oleh beberapa batangan logam yang dimasukkan melewati slot-slot yang ada pada rotor motor industri, kemudian pada setiap bagian disatukan oleh cicin yang membuat batangan logam dihubung singkat dengan batangan logam yang lain. Motor ini bekerja berdasarkan industri eketromagnetik dari stator ke rotor, dimana arus pada rotor yaitu merupakan arus yang terindustri akibat adanya perbedaan leratif antara putaran rotor dengan medan putaran (Rotating Magneting Field) yang dihasilkan oleh stator [7]. Magnet bergerak dikarenakan adanya pelampung yang mendorong magenet untuk bergerak naik turun.…”

Pengaturan kecepatan motor induksi tiga fasa dengan direct torque control menggunakan jaringan saraf tiruan

“…Keunggulan motor induksi konstruksinya sederhana dan kokoh, harga murah, handal, tenaga yang besar dengan daya listrik yang rendah dan perawatan mudah [4]. Sedangkan kelemahannya yaitu, sulitnya mengatur kecepatan karena karakteristiknya bersifat nonlinear, terutama resistansi rotor yang memiliki nilai yang bervariasi untuk kondisi operasi yang berbeda, sehingga tidak dapat mempertahankan kecepatannya secara konstan bila terjadi perubahan beban [5], [6], [7]. Untuk mendapatkan kecepatan yang konstan serta memperbaiki kinerja motor induksi maka dibutuhkan suatu rangkaian kontrol [8].…”
