TRIM, LINEARIZATION AND PID CONTROLLER DESIGN FOR A MULTI-PURPOSE FIXED-WING AIRCRAFT

Fixed-wing unmanned aerial vehicles (UAVs) can be used for numerous civilian purposes such as passenger transport, cargo transport, crop dusting, forest fire fighting, and aerial photography. This research presents the trim, linearization, and proportional integral derivative (PID) controller design of a fixedwing aircraft. Modeling and simulation studies were carried out using MATLAB/Simulink. The created model takes elevator, aileron, rudder, and throttle as input and produces angles, angular rates, and position as output. The analyzed simulation studies confirm the success of the modeling and controller design.
