Abstract

Bu yayında ikinci derece zaman gecikmeli
sistemlerin kararlılığı ve performansı için oransal türev denetleyicinin
analitik tasarımı şeması gösterilmiştir. Bu sistem için Bode’nin ideal transfer
fonksiyonunun karakteristiğinden esinlenerek kazanç kesim frekansı ve faz payı
gereksinimleri ele alınmıştır. Daha sonra bu gereksinimler denetleyicinin
parametrelerini elde etmek için kullanılmıştır. Bu çalışmada önerilen yöntem
sözü edilen sistemler için genelleştirilmiş denklemleri vermektedir. Önerilen
yöntemle analitik olarak türetilen formüller literatürde var olan sistemler
üzerinde denenmiş ve sonuçlar grafiksel olarak gösterilmiştir. Bu ayarlama
yönteminin istenen kazanç kesim frekansı ve faz payı özelliklerini sağladığı
gösterilmiştir.

Analytical Design of PD Controllers for Time Delay Systems in the Second Order

Abstract

This paper intends to present the design scheme
of a Proportional Derivative controller for stability and performance of time
delay systems in the second order. Inspired from Bode’s ideal system
characteristics, phase margin and gain crossover frequency specifications are
considered for the system. Then, these specifications are used to obtain the
parameters of the controller. The method proposed in the study achieves general
computation equations for mentioned systems. Analytically derived formulas by
the proposed method are tested with existing plants in the literature and the
results are illustrated graphically. It is shown that the tuning method
satisfies desired gain crossover frequency and phase margin specifications.

Keywords

SOPTD plant, PD controller, gain crossover frequency, phase margin.
