In this paper, the longitudinal dynamics and automatic control system design processes of Hezarfen UAV for longitudinal flight have been discussed. Hezarfen UAV is a prototype UAV aircraft 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. In the first part of the paper, longitudinal dynamic properties of Hezarfen UAV have been presented. Following to that, automatic control system for the longitudinal flight (autopilot) has been designed using classical PID control algorithm, in the second part of the paper. In the third part, as an alternative, one-degree of freedom H inf. Loop Shaping Robust Control system has been suggested and implemented to the system. Obtained results are given in comparison and presented in the conclusions part of the paper.
