Abstract

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 increase the speed
control performance of IM. In the study, speed control of IMs was realized by
Difference Frequency (DF). The Scalar Control (SC) method was used in IM speed
control. In order to increase the performance of SC, the frequency information
received from IM was compared with the reference frequency. The resulting DF
was applied to the system input again. For the performance analysis of the
study; SC, PI + SC and DF + SC methods were compared. The results obtained from
the study simulated in Matlab software show that the proposed method can be
used in speed control. 

Keywords
