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.

In this study, Newton-Raphson Based (NRB) scalar speed control (SSC) is recommended to control the speed of Induction Motors (IM). As is known, the Newton-Raphson method, which is often used in numerical analysis, is one of the methods that provide a rapid convergence of the desired value. In this study, the frequency value required for the desired speed value is calculated by Newton-Raphson method. Three different models including Newton-Raphson Based + Scalar Speed Control (NRB_SSC), Difference Speed + NRB_SSC (DS_NRB_SSC), DS + NRB_SSC + Difference Frequency (DS_NRB_SSC_DF) were used for optimization tests. Simulation of the work was done in Matlab/Simulink programme. According to obtained test results DS_NRB_SSC_DF has produced better results.

ÖZETGünümüzde Yapay Sinir Ağları (YSA), farklı uygulamalarda, doğrusal olmayan birçok problemin çözümünde kullanılmaya başlanmıştır. Bu çalışmada, Doğrusal Hareketli Sürekli Mıknatıslı Senkron Motorun (DHSMSM) YSA tabanlı skaler (V/f) hız denetimi deneysel olarak gerçekleştirilmiştir. Skaler denetim için ürün modeli LG-SV022IG5A-4 olan değişken frekanslı sürücü kullanılmıştır. Bu sürücünün frekansı C# programlama diliyle hazırlanan YSA ile denetlenerek motorun hız denetimi gerçekleştirilmiştir. DHSMSM, farklı hız ve yük koşullarında çalıştırılarak elde edilen deneysel sonuçlar sunulmuş ve motorun hız denetimindeki başarım analizi yapılmıştır.Anahtar kelimeler: Doğrusal hareketli motor, DHSMSM, YSA, skaler denetim, hız denetim NEURAL NETWORK BASED SCALAR SPEED CONTROL OF LINEAR PERMANENT MAGNET SYNCHRONOUS MOTOR ABSTRACTNowadays, Artificial Neural Networks (ANN), in different applications, have been used in solving many problems of non-linear. In this study, ANN based Scalar (V / f) speed control of Linear Permanent Magnet Synchronous Motor (LPMSM) was carried out experimentally. For scalar control, variable frequency drive that is product of model LG-SV022IG5A-4 are used. This drive is controlled by the frequency of the C # programming language prepared by the ANN and the motor speed control was performed. Obtained experimental results by running LPMSM at different speed and load conditions were presented and analysis of success in motor speed control was performed.
