Sürekli mıknatıslı senkron motor SMSM hız denetimi elektrik makinalarının önde gelen kontrol problemlerindendir. Çalışmada sürücü tasarımında motorun matematiksel modeli ve sistemin doğal frekansı göz önünde bulundurulmuştur. Lineer olmayan SMSM modellenmesi için üç fazlı yapıdan iki eksenli yapıya sırasıyla Clarke ve Park dönüşümleri ile geçilmiştir. Bu dönüşümle denklemlerdeki doğrusal olmayan yapı devam etmektedir ancak yapılacak olan kontrol stratejisi ile sistemde birbirine bağlı parametrelerin ayrıklaştırılması sağlanmıştır. Çalışmada hem hız denetimcisi tasarımında hem de akım-gerilim dönüşümlerinde doğal frekanstan yararlanılmıştır. Sistemin hız çevriminin kontrolü katsayı-integral PI denetleyici ve bulanık mantık denetleyici BMD ile sağlanmıştır. MATLAB/SIMULINK ortamındaki benzetim sonuçları hem yapay zekanın başarımını hem de doğal frekans yolu ile tasarlanmış akım-gerilim dönüştürücülerinin başarımını görsel olarak sunmuştur

Natural Frequency and Fuzzy Logic at Permanent Magnet Synchronous Motor Speed Control

Öz

Permanent magnet synchronous motor speed control is one of the central problems in electrical machine control. Mathematical model of the machine and natural frequency of the system are taken into consideration for controller design. The nonlinear three phase system is transferred into 2 axis plane by using Clarke and Park transmissions. After this one, nonlinear system form is not change. But the control strategy can separate the system parameters, which are related to each other. Natural frequency was used for both of speed controller design and current-voltage transformer design operations. The speed loop of the system was controlled by proportionalintegral PI and fuzzy logic controller. The designed controllers and drive circuit was validated in MATLAB/SIMULINK environment and the simulation results present graphical results, which are proofs of the designed controllers and artificial intelligence.
