Abstract

In this study, it has proposed to adjust the parameters of the Linear Effective Distortion Prevention Controller (LADRC) with the Symbiotic Organism Search (SOS) algorithm. The parameters of LADRC were determined by both traditional methods and Symbiotic Organism Search (SOS) algorithm, and comparative analyzes were performed on the speed control performances of permanent magnet direct current motor (PMDCM). Two different reference signals have applied to both systems and monitoring performances were presented graphically and also in the form of a table containing the mean of the squared errors. Simulation-based results have shown that LADRC, which already has a powerfull control performance, can create a faster system response, especially in steep transitions and deterioration points in the reference mark, by adjusting its parameters offline with the SOS algorithm. This situation has caused a decrease in total tracking error and revealed that SOS optimized LADRC has a better tracking performance.

Doğrusal Etkin Bozucu Engellemeli Denetleyici Parametrelerinin SOS Algoritması ile Ayarlanması

Abstract

Bu çalışmada, Doğrusal Etkin Bozulma Engellemeli Kontrolörün (LADRC) parametrelerinin Simbiyotik Organizma Araması (SOS) algoritması ile ayarlanması önerilmiştir. LADRC'nin parametreleri hem geleneksel yöntemler hem de Simbiyotik Organizma Araması (SOS) algoritması ile belirlenerek sabit mıknatıslı doğru akım motorunun (PMDCM) hız kontrol performansları üzerinde karşılaştırmalı analizler yapılmıştır. İki farklı referans işareti her iki sisteme de uygulanmış ve izleme performansları grafiksel olarak ve ayrıca karesel hatalarının ortalamasını içeren tablo biçiminde sunulmuştur. Benzetim temelli sonuçlar zaten oldukça güçlü bir kontrol performansına sahip olan LADRC’nin parametrelerinin SOS algoritması ile çevrim-dışı olarak ayarlanması sonucunda özellikle referans işaretindeki dik geçişler ve bozulma noktalarında daha hızlı bir sistem cevabı oluşturabildiğini göstermiştir. Bu durum toplam izleme hatasının azalmasına neden olmuş ve SOS ile optimize edilmiş LADRC’nin daha iyi bir izleme performansına sahip olduğunu ortaya koymuştur.
