Çok Amaçlı Atomik Yörünge Arama Algoritması ile Metasezgisel FIR Filtre Tasarımı

Öz

Bu çalışmada, MATLAB ortamında yüksek performanslı ve düşük dereceli FIR filtreleri tasarlamak için yeni önerilen metasezgisel algoritmalardan biri olan atomik yörünge araması kullanılmıştır. Tasarlanan filtrenin performans parametreleri verilen literatür ile karşılaştırılmıştır. Filtre tasarımının amaç fonksiyonu, geçiş bandı dalgalanmalarının ve durdurma bandı dalgalanmalarının minimizasyonunu, durdurma bandı kenar frekans zayıflamasını, tahmini frekans yanıtı ile ideal filtre yanıtı arasındaki hataların karesel toplamını içerir. Karşılaştırma sonucu, önerilen yöntemin çoğu algoritmadan daha iyi performans gösterdiğini ve pratik uygulamalarda kullanılabileceğini göstermektedir.

Metaheuristic FIR Filter Design with Multi-Objective Atomic Orbital Search Algorithm

Abstract

In this study, atomic orbital search, one of the newly proposed metaheuristic algorithms, is used to design high-performance and low-order FIR filters in MATLAB. The performance parameters of the designed filter were compared with the given literature. The objective function of filter design includes minimization of pass band ripples and stopband ripples, stop band edge frequency attenuation, square sum of the errors between the estimated frequency response and the ideal filter response. The comparison result shows the proposed method performs better than most algorithms and can be used in practical applications.
