Abstract:

Some missions require efficient device to minimize the risk of personnel aviator. Unmanned aerial Vehicle (UAV) have sufficient ability to be effective in overcoming these difficulties with the less risks and costs. Many of uses UAV for various civilian and military activities such as border surveillance mission, as well as aerial photography necessitating the ability of UAV to fly independently with high stability. Reliable performance of the UAV is determined by the controller will control the UAV with high accuracy and ease of control.
Autopilot system requires a controller with the ability to manage payload sensors and process it to be passed as output to the servo aileron, rudder and elevators plane. Usage of AVR-XMEGA microcontroller is a good choice in its use as the main control device or Onboard Data Handling (OBDH).
Autopilot system created has two modes, namely a manual mode that uses a PWM input from the RC receiver to directly forward to the servo and auto mode using IMU sensor readings and process PID to maintain a stable position of the aircraft. The results of the second test mode to test tick interval from input to output generates the data input and output processes occur at the same tick that the system is running in real time.
