Abstract

Bu çalışmada, asenkron motorun hız kontrolünde kesirli PI^λ yöntemi, sınırlı hafızaya sahip olan bir dsPIC mikrodenetleyicisi kullanılarak gerçekleştirilmiştir. Kesirli integralin hesaplanması işleminde kullanılan hata fonksiyonu ve ağırlık fonksiyonu veri setleri sadece son 50 veriyi kullanacak şekilde sınırlandırılmıştır. Bu sınırlandırma işlemi kesirli kontrolörün dsPIC mikrodenetleyicisinde kullanılabilmesini sağlamıştır. Farklı k_p, k_i ve λ değerleri için hız kontrolü deneyleri gerçekleştirilmiştir. Sonuçlar tablolarda ve şekillerde sunulmuştur.

Fractional Order PIλ Controller Application for Limited Memory System

Abstract

In this study, the fractional order PIλ controller has been realized for induction motor speed control system with using dsPIC microcontroller which has a limited memory device. To computation of fractional order integral, the error function and the weight function data sets has been limited for using only last 50 data. This limitation has provided the fractional order controller to be used in the dsPIC microcontroller. The experiments are realized by using different kp, ki and λ values for speed control. The results are presented in tables and figures.
