DYNAMIC MODELING AND CONTROL OF AN ELECTRO-MECHANICAL FIN LOADING SYSTEM

Öz

In this study, the design of an electro-mechanical fin loading system which is utilized to simulate the effects of the aerodynamic moment occurring in an atmospheric flight on a missile system is dealt with. In this extent, the dynamic modeling of the dedicated loading system is constructed and then the control system is designed on that model. As the control algorithm, the classical control system operating with regard of the PID (proportional plus integral plus derivative) control action and the robust control system designed according to the H∞ norm are taken into consideration. Once the mentioned control systems are built, the relevant computer simulations are performed with the inclusion of a realistic control actuation system model in accordance with the consistent numerical values of the necessary parameters. As a result of this work, it is observed that the robust control system yields more satisfactory results than its classical counterpart even under more severe conditions.

Elektromekanik Eyletimli Bir Kanat Yükleme Cihazının Dinamik Modellemesi ve Denetimi

Öz

Bu çalışmada, atmosfer içerisinde uçan bir füzeye etkiyen aerodinamik moment etkisinin yerde benzetimini yapmak amacıyla tasarlanan elektromekanik eyletimli bir kanat yükleme cihazının tasarımı ele alınmaktadır. Bu kapsamda, göz önüne alınan kanat yükleme cihazının dinamik modeli çıkarılmış ve ardından bu model üzerine denetim sistemi tasarlanmıştır. Denetim sistemi olarak, PID (oransal, tümlevsel ve türevsel) denetim işlemini esas alan klasik denetim sistemi ile H∞ normunu esas alarak sentezlenen gürbüz denetim sistemi uygulanmıştır. Denetim sistemi oluşturulduktan sonra, ilgili parametreler için belirlenen tutarlı sayısal değerler kullanılarak modellenen gerçekçi bir kontrol tahrik sistemi de toplam sistem şemasına dahil edilerek bilgisayar benzetimleri gerçekleştirilmiştir. Benzetimler sonucunda, çok daha zorlu işletim koşulları altında dahi gürbüz denetim sisteminin klasik denetim sistemine nazaran daha tatminkâr çıktılar ürettiği gözlenmiştir.
