Application of H inf. Loop Shaping Robust Control system design on longitudinal dynamics of Hezarfen UAV with classical PI(D) and pole placement methods: A comparison analysis - (S/T)

In this paper, beside longitudinal dynamic properties of Hezarfen UAV, several automatic control system designs including H inf. Loop Shaping Robust Control, Classical PID control and Pole Placement control methods have been discussed. Hezarfen is a prototype UAV which is being designed and going to be build-up for the first time in co-operation with Istanbul Technical University, Faculty of Aeronautics and Astronautics. The first part of the paper is dedicated to derivation of longitudinal dynamic model of Hezarfen UAV. Following to this, in the second part, not only the classical PID and Pole Placement methods, but also powerful H inf. Loop Shaping Robust Control method has been implemented to the longitudinal dynamics of Hezarfen UAV system and obtained results have been given in comparison at the end of the paper.
