ABSTRAK Pengaturan kecepatan merupakan salah satu permasalahan yang terjadi pada motor induksi. Motor induksi merupakan motor yang paling umum digunakan didunia industri, bisnis transportasi dan lain-lain. Keunggulan motor induksi ialah memiliki rancangan yang sederhana dan kuat, harganya murah, efisiensi tinggi, power factor cukup baik, dan perawatannya lebih mudah. Pada penelitian ini metode pengaturan kecepatan yang digunakan adalah metode Direct Torque Control (DTC) dimana DTC mampu mengatur fluks dan torsi secara langsung serta dapat dilakukan tanpa menggunakan sensor kecepatan. Adapun kontrol yang digunakan yaitu Jaringan Saraf Tiruan (JST) menggunakan Model Reference Control (MRC). Respon plant mampu beradaptasi terhadap nilai dari kecepatan referensi yang diberikan. Hasil pengujian menunjukkan bahwa kontrol JST mampu mengendalikan motor induksi dengan respon waktu yang cukup baik, hal ini dapat dilihat saat diberi kecepatan referensi sebesar 150 rad/s didapatkan nilai time constan sebesar 0,8693 s, rise time sebesar 1,2917 s, settling time sebesar 1,5536 s, time delay sebesar 0,622 s serta error steady state sebesar 0,9%. ABSTRACT Speed regulation was one of the problems that occurred in induction motors. induction motors were the most commonly used motors in industry world, transportation business and others. The advantages of an induction motor were it had a simple and robust design, low cost, high effeciency, good power factor, and easier maintenance. In this study, the speed regulation method used was the Direct Torque Control (DTC) method where DTC was able to regulate flux and torque directly and it can be done without using a speed sensor. The control used was Artificial Neural Networks (ANN) using Model Reference Control (MRC). The plant response was able to adapt to the value of reference speed given. The test results showed that the ANN control was able to control the induction motor with a good response time. It can be seen when it was given a reference speed of 150 rad/s, the time constant value of 0.8693 s, rise time of 1.2917 s, settling time of 1.5536 s, delay time of 0.622 s and error steady state of 0.9%.

ABSTRAKSuatu Motor induksi tiga fasa merupakan alat penggerak listrik yang banyak digunakan di industry. Sistem yang akan dikembangkan dalam penelitian ini salah satunya adalah pengendalian kecepatan motor induksi tiga fasa dengan pemodelan system Direct Torque Control (DTC) dengan pengontrol kecepatan menggunakan Neuro-Fuzzy Controller, hasil yang diperoleh dari pengaturan kecepatan yaitu untuk mencapai keaadan steady hanya membutuhkan waktu 1 sampai 2 sekon dengan rata-rata eror steady 0,175% dengan rata-rata rise time 0,855 detik dan rata-rata overshoot 0,488%. Dengan pemodelan system Direct Torque Control (DTC) menggunakan Neuro-Fuzzy control ini mampu mengatasi kelemahan pada kecepatan motor induksi serta menghasilkan performa kendali yang tinggi, dengan memperkecil overshoot serta menurunkan presentase error steady state dibawah 1%, serta rise time dan settling time rata-rata di bawah 1 detik, sehingga jauh lebih baik dibandingkan dengan menggunakan PI controller.Kata kunci: DTC, Motor Induksi, Neuro-Fuzzy ABSTRACTA three-phase induction motor is an electric drive that is widely used in industry. One of the systems that will be developed in this research is the speed control of a three-phase induction motor by modeling the Direct Torque Control (DTC) system with a speed controller using a Neuro-Fuzzy Controller, the results obtained from speed regulation are that to achieve steady state it only takes 1 to 2 hours. 2 seconds with an average steady error of 0.175% with an average rise time of 0.855 seconds and an average overshoot of 0.488%. By modeling the Direct Torque Control (DTC) system using Neuro-Fuzzy control, it is able to overcome the weakness in the speed of the induction motor and produce high control performance, by reducing overshoot and reducing the steady state error percentage below 1%, as well as the average rise time and settling time. the average is under 1 second, so it is much better than using a PI controllerKeywords: DTC, Induction Motor, Neuro-Fuzzy

“…Several methods were developed, namely the vector control method and then developed into several other methods such as Field Oriented Control (FOC) and Direct Torque Control (DTC) [2]. Both of these methods can be used as speed regulation for 3-phase induction motors, each with its own advantages and disadvantages.…”

3-phase induction motors as electric drives are very popular due to their lower prices, sturdy construction and maintenance-free. Induction motors also have non-linear characteristics so that they are difficult to regulate. In this study the vector method is used as a field setting on an induction motor, this method can make the coupled system a decoupled system. The test results show that the value of the field current (iqs) given to the Field Oriented Control (FOC) system affects the torque and rotation of the rotor. the greater the value of the field current (iqs), the smaller the torque value so that the rotor speed on the motor increases. Under the condition that the motor is loaded with 5 N and iqs 1 A, the electromagnetic torque value is 14.05 Nm, while at the 5 N and iqs 5 A load conditions, the electromagnetic torque value is 13.63 Nm.
