Rancang Bangun Speed Sensorless Control untuk Motor Induksi 3 Fasa Menggunakan Kontroler PID

Pengendali kecepatan motor induksi tiga fasa sangat diperlukan untuk mengurangi biaya listrik dan slip dalam menjalankan motor induksi. Untuk mencapai peforma terbaik diperlukan sistem kendali yang berjalan cepat, stabil, akurat, dan mampu beradaptasi dengan baik terhadap perubahan kecepatan. Penelitian ini menggunakan metode Speed Sensorless Control mengendalikan keluaran inverter ke motor induksi untuk mengendalikan kecepatan motor induksi. Metode Speed Sensorless Control merupakan metode yang menggunakan Speed Sensorless Estimator dengan algoritma Disturbance Observer sebagai feedback pengendalian dan Proportional Integral Derivatif (PID) kontrol dalam mengendalikan kecepatan motor. Kontroler PID dapat dituning secara adaptif dan manual dengan menggunakan metode tuning PID Cohen-Coon dan Ziegler Nichols untuk mendapatkan respon pengendalian yang cepat dan akurat dengan overshoot yang minimal. Hasil yang didapatkan adalah Speed Sensorless Control memiliki respon yang akurat yakni dengan steady state error 2.32%, cepat yakni dengan rise time 4.62 detik, settling time 18.31 detik, overshoot 11.50%, dan mampu beradaptasi pada perubahan set point. ======================================================================================================================== Three phase induction motor speed regulation system is needed to reduce electricity costs and slip in running an induction motor. To get the best performance, a control system must run fast, stable, accurate, and able to adapt well to changes in speed. This study uses the Speed Sensorless Control method which directly controls the output of the inverter to the induction motor to control the speed of the induction motor. The Speed Sensorless Control method is a method that uses a Speed Sensorless Estimator with the Disturbance Observer algorithm as control feedback and Proportional Integral Derivative (PID) control in controlling motor speed. PID controller can be tuned adaptively and manually using PID tuning Cohen-Coon and Ziegler-Nichols method to obtain a fast and accurate control response with minimal overshoot. The results obtained are that Speed Sensorless Control has an accurate response with a steady state error of 2.325%, fast with a rise time of 4.62 seconds, settling time of 18.31 seconds, overshoot of 11.50%, and can adapt to changes in set point.data that has occurred in Indonesia.
