Otomatik Gerilim Regülatörü Sistemi için Farklı Optimizasyon Teknikleri Ayarlı Denetleyici Tasarımı

Otomatik gerilim regülatörü (OGR), güç sistemlerindeki senkron generatörün uç gerilimini kontrol etmek ve düzenlemek amacıyla kullanılan önemli bir kontrol sistemidir. Bu amaçla, bu çalışmada, OGR sistemi için çeşitli meta-sezgisel optimizasyon teknikleri ayarlı denetleyici tasarımı gerçekleştirilmiştir. OGR sisteminde denetleyici olarak oransal – integral – türev (PID) denetleyici kullanılmıştır ve bu denetleyicinin parametreleri son yıllarda geliştirilmiş olan açlık oyunları algoritması (HGS), INFO algoritması ve goril birlikleri optimizasyonu (GTO) gibi optimizasyon teknikleri yardımıyla optimal olarak ayarlanmıştır. Amaçlanan optimizasyon teknikleri ayarlı PID denetleyicisinin geçici zaman performansları simülasyon çalışmaları yardımıyla incelenmiştir ve aşma değeri, yükselme süresi, yerleşme süresi gibi performans değerleri açısından karşılaştırılmıştır. Ek olarak, denetleyiciler arasında kutup/sıfır analizi, bode analizi ve gürbüzlük analizi açısından karşılaştırma gerçekleştirilmiştir. Elde edilen sonuçlardan PID denetleyicinin parametrelerinin ayarlanması amacıyla kullanılan HGS, INFO ve GTO optimizasyon tekniklerinin birbirine yakın ve dikkate değer performans gösterdiği görülmektedir.

The Controller Design Tuned by Numerous Optimization Techniques for Automatic Voltage Regulator System

The automatic voltage regulator (AVR) is an important control system used to control and regulate the terminal voltage of the synchronous generator in power systems. For this purpose, in this study, various meta-heuristic optimization techniques tuned controller design for the AVR system has been carried out. A proportional – integral – derivative (PID) controller is used as the controller in the AVR system and the parameters of this controller are optimally adjusted using optimization techniques such as the hunger games algorithm (HGS), INFO algorithm and gorilla troops optimization (GTO) developed in recent years. The transient time performances of the PID controller tuned to the proposed optimization techniques were investigated with the help of simulation studies and compared in terms of performance values such as overshoot, rise time, settling time. In addition, comparisons were made between the controllers in terms of pole/zero analysis, bode analysis and robustness analysis. From the results obtained, it is seen that the HGS, INFO and GTO optimization techniques used for adjusting the parameters of the PID controller have close to each other and remarkable performance.
