Üçüncü derece zaman gecikmeli sistemler için PI denetleyicilerin analitik tasarımı

Bu yayında üçüncü derece ve zaman gecikmesi içeren sistem modellerinin kararlılığı, performansı ve dayanıklılığı için analitik bir oransal integral denetleyici tasarım yöntemi sunulmuştur. Denetleyici tasarımı, ideal bir sistemin frekans tepkilerini ele alarak denetlenmek istenen sistemin arzu edilen kazanç ve faz özelliklerini sağlaması üzerinde yoğunlaşmıştır. Sözü edilen özellikleri sağlayan oransal integral denetleyici parametrelerini veren denklemler adım adım oluşturulmuştur. Bu denklemler, söz konusu sistemler için genelleştirilmiş eşitlikleri içermektedir. Araştırmacı, bu yöntem sayesinde üçüncü derece zaman gecikmeli sistemler için istenen kazanç kesim frekansı ve faz payı değerlerini sağlayabilmektedir. Bu sayede, Bode grafiği nispeten ayarlanabilmekte ve sistemin performansı ve dayanıklılığı artırılabilmektedir. Aynı zamanda önerilen denklemlerle sistem kararlığı da elde edilebilmektedir. Yayında sunulan yöntemle elde edilen denklemler iki farklı model üzerinde uygulanmıştır. Tüm sonuçlar grafiksel olarak ve tablolarla gösterilmiştir.
