Hidrolik Eyletimli Bir Kanatçık Yükleme Cihazının Dinamik Modellemesi ve Tümlevli Geri Adımlama Yöntemi Kullanılarak Denetimi

Kanatçık yükleme cihazları, havacılık uygulamalarında kullanılan tahrik (eyletim) sistemleri üzerindeki harici yük etkisi benzetimlerini yapmak amacıyla geliştirilmektedir. Bahsedilen uygulamalarda, kanatçık tahrik sistemlerinin aerodinamik kuvvet ve momentler altındaki başarımları ele alınması gereken önemli hususlardan biridir. Göz önüne alınan azami kuvvet ve moment değerlerine elektromekanik, hidrolik veya pnömatik eyletimli olabilmektedir. Bant genişliği gereksinimi, eyletim şekline karar vermedeki bir diğer belirleyici unsur olarak öne çıkmaktadır. Bu bağlamda, daha yüksek kuvvet ve moment oluşturma kapasitesi ve yüksek bant genişliği dolayısıyla hidrolik eyletim daha avantajlı bir seçenek olarak belirmektedir. Bu çalışmada, hidrolik eyletimli bir kanatçık yükleme cihazı için tümlevli geri adımlama yöntemi kullanılarak denetim sistemi tasarlanması hususu ele alınmaktadır.

Dynamic Modeling and Control of a Hydraulic Fin Loading System Using Integral Backstepping Method

Fin loading systems are utilized to simulate the effects of the external inputs on actuation systems in aerial applications. In those systems, the performance of the fin actuation systems subject to aerodynamic force and moment effects is one of the major issues to be handled. Depending on the amount of the maximum force and torque values, the loading systems are in the type of electromechanically-, hydraulically-, or pneumaticallyactuated. The bandwidth requirement is another determining factor in deciding on the type of the actuation. In this scene, the hydraulic actuation systems are more advantageous than the others because of their large force and moment execution capabilities as well as high bandwidth properties. In this study, the issue of designing a control system for a hydraulicallyactuated fin loading system is investigated regarding the integral backstepping method.
