Abstract

Unmanned aerial vehicles (UAV) are taking more attention in both civilian and army applications in the world. One of the most important thing in UAV applications is to make an autonomous, fast and stable control of a UAV. In this study, one of the fixed wing UAV model (Ultrastick -25e) is analyzed and aerodynamic parameter coefficients of the UAV model which needed for dynamic equations are acquired from literature. For that reason, firstly, as a classical control techniques of a fixed wing UAV, PID controller is applied and transfer functions of different state variables are derived by using state-space model. PID gains of state variables according to different control inputs are obtained by using Matlab tuning and Ziegler-Nichols methods. Optimum PID gains, rise time, settling time, peak overshoots of the roll, pitch and yaw dynamics are obtained. Future studies will give a chance to compare classical PID controller results and modern control techniques in terms of altitude, roll and heading angle controller of the UAV model.
