PEMODELAN TRANSFORMASI DIRECT QUADRATUR (D-Q) PADA KENDALI KECEPATAN MOTOR INDUKSI 3 FASA DENGAN METODE VECTOR CONTROL

The application of the 3 phase induction motor is increasingly developing, this has led to research on speed regulation motors also growing, because use in industry and especially hybrid vehicles being developed. However, there are several disadvantages an motor, one which non-linear parameter characteristics, rotor resistance, varies value for different operating conditions, so that it cannot maintain its constantly when a load changes. Therefore, get constant better system performance against changes, controller needed. This study aims implement vector control method following reference speed. In modeling, parameters (ia, ib ic) will be transformed into direct quadrature (dq) where setting field size torque can adjusted separately. implementation results, seen used as approach regulating motor.
