DOĞRUDAN MOMENT KONTROLÜNDE HIZ KESTRİMİ İÇİN KALMAN FİLTRESİ UYGULAMASI

Öz

Bu çalışmada, sağlıklı ölçümlerin alınamadığı durumlarda asenkron motorun, doğrudan moment kontrol yöntemi ve genişletilmiş kalman filtresi kullanılarak hızı kestirilmiştir. Doğrudan moment kontrolü yönteminin bileşenleri olan anahtarlama tablosu, elektromanyetik moment ve stator akı değerlendiricileri, moment denetleyicisi ve akı denetleyicisi incelenerek farklı anahtarlama frekanslarındaki çıkış parametreleri için benzetim çalışması yapılmıştır. Genişletilmiş kalman filtresinin doğrudan moment kontrolünde uygulanması sırasında farklı anahtarlama frekansları için kayıp ilişkisi tartışılmıştır.

EXTENDED KALMAN FILTER APPLICATION IN DIRECT TORQUE CONTROL FOR SPEED ESTIMATION

Öz

In this study, in cases where accurate measurements could not be taken, the speed of the asynchronous motor was estimated using the direct torque control method and extended Kalman filter. The switching table, stator flux and electromagnetic moment evaluators, flux and torque controller, which are the components of the direct torque control method, were examined and the output parameters at different switching frequencies were simulated. The loss relationship for different switching frequencies during the application of the extended Kalman filter in direct torque control is discussed.
