Fark Frekans ile İndüksiyon Motorun Skaler Hız Denetimi

Elektrik motorlarının hız denetimi geçmişten günümüze pek çok araştırmacının ilgisini çekmiştir. Elektrik motor çeşitlerinden biri olan Indüksiyon Motor (IM) ya da Asenkron Motor (ASM) farklı yüklerde nominal hızın gerisinde kalmaktadır. Bu çalışmada IM’nin hız denetim başarımını arttırmak amacıyla yapılmıştır. Yapılan çalışmada IM’lerin hız denetimi Fark Frekans (FF) ile gerçekleştirilmiştir. IM hız denetiminde Skaler Denetim (SD) yöntemi kullanılmıştır. SD’nin başarımını arttırmak için IM’den alınan frekans bilgisi referans frekans ile karşılaştırılmıştır. Elde edilen FF tekrar sistem girişine uygulanmıştır. Çalışmanın performans analizi için; SD, PI + SD ve FF + SD yöntemleri karşılaştırılmıştır. Analiz sonuçları tablo ve grafikler ile sunulmuştur. Matlab yazılımında benzetimi gerçekleştirilen çalışmadan elde edilen sonuçlar önerilen yöntemin hız denetiminde kullanılabileceğini göstermektedir.

Scalar Speed Control of Induction Motors with Difference Frequency

Speed monitoring of electric motors has attracted the attention of many researchers from past to present. Induction Motor (IM),which is one of the electric motor types, falls behind the nominal speed in different loads. This study was conducted to increasethe speed control performance of IM. In the study, speed control of IMs was realized by Difference Frequency (DF). The ScalarControl (SC) method was used in IM speed control. In order to increase the performance of SC, the frequency information receivedfrom IM was compared with the reference frequency. The resulting DF was applied to the system input again. For the performanceanalysis of the study; SC, PI + SC and DF + SC methods were compared. The results obtained from the study simulated in Matlabsoftware show that the proposed method can be used in speed control.
