Abstract

Makalah ini membahas observer yang digunakan untuk identifikasi kecepatan motor induksi tiga fasa. Estimasi kecepatan oleh observer hanya memerlukan masukan tegangan dan arus. Observer yang digunakan untuk identifikasi berbasis pada ANFIS yang dimodifikasi dengan Least Square Estimator (LSE) untuk menentukan parameter konsekuen pada alur maju dan dengan metoda Steepest Descent (SD) untuk memperbarui parameter premis pada alur mundur. Modified ANFIS observer dirancang untuk menentukan pola dari fluksi rotor dan kecepatan sudut rotor. Hasil simulasi pada Modified ANFIS Observer yang telah dilakukan menggunakan 5000 data pembelajaran, time sampling = 0,00005 detik pada kecepatan 500 rpm didapatkan, Mean Square Error (MSE) fluksi direct -0.3106.102%, MSE fluksi quadratur -0.3206.102%, dan MSE kecepatan angular -0.4922.102. Dari hasil tersebut menunjukkan bahwa Modified ANFIS Observer mampu melakukan identifikasi terhadap fluks rotor dan kecepatan rotor motor induksi dengan sangat baik.

Induction motors are widely used in industry, because they are more rugged and reliable than de motors, what-more by using field oriented control method in an induction motor, it's as though as the de motors. To control induction motor which parameters are uncertain, for this case considered the controller is of known structure and uses the value of the state variable. But some state variables cannot be measured, such as rotor flux. A modified ANFIS observer is used estimate the flux, for the purpose of identifying motor induction speed. Modified ANFIS observer for induction motor based on ANFIS which modified with Least Square Estimator to up date the consequent parameters in forward pass and Steepest Descent method to up date the premise parameters in backward pass. The result show that modified ANFIS observer can estimate the pattern of flux rotor and rotor angular speed. The proposed modified ANFIS observer has shows good performance.
