Abstract
Penggunaan sensor kecepatan dalam pengendali kecepatan motor induksi tiga fasa memengaruhi keandalan dari motor induksi. Selain itu, mesin penggerak yang sering digunakan pada industri adalah motor induksi tiga fasa. Sehingga, diperlukan speed sensorless control untuk motor induksi agar mencapai performa terbaik. Penelitian ini menggunakan discrete disturbance observer sebagai pengumpan balik pada speed sensorless control dan merancang kontrol yang mampu untuk mengatasi perubahan beban torsi yang diberikan.. Kontroler yang digunakan pada metode ini adalah diskrit PI dengan metode tuning Cohen Coon dan Ziegler-Nichols. Tujuan penggunaan kedua metode tersebut adalah menemukan metode tuning yang lebih baik dalam melakukan kontrol terhadap perubahan beban torsi dengan tujuan mendapatkan respon pengendalian yang cepat dan akurat, serta meminimalkan overshoot. Hasil menunjukkan bahwa metode tuning Cohen Coon lebih baik digunakan pada pemberian beban 170 Watt dan 200 Watt dengan variasi kecepatan 800 RPM dan 1200 RPM dengan rata-rata error steady state sebesar 0.32%.

The use of speed sensors in three-phase induction motor speed controllers reflects the resolution of the induction motor. Apart from that, the driving machine that is often used in industry is a three-phase induction motor. So, sensorless speed control is needed for induction motors to achieve the best performance. This research uses a discrete Disturbance observer as feedback for sensorless speed control and designs a control that is able to overcome changes in the applied torque load. The controller used in this method is a discrete PI with the Cohen Coon and Ziegler-Nichols tuning method. The aim of using these two methods is to find a better tuning method for controlling changes in torque load with the aim of getting a fast and accurate control response, as well as minimizing overshoot. The results show that the Cohen Coon tuning method is better used when providing loads of 170 Watts and 200 Watts with speed variations of 800 RPM and 1200 RPM with an average stable state error of 0.32%.
