Development of Automatic Take Off and Smooth Landing Control System for Quadrotor UAV

This paper covers the development of automatic takeoff and smooth landing control system for UAV Quadrotor. This paper includes development, simulation, mathematical modeling and experimental results of flight test. Developed UAV model has a system to stabilize the quadrotor. Altitude stabilization in quadrotor make the quadrotor can perform take off and smooth landing perfectly and can avoid crash during landing which was proved during experiment. Yaw, pitch, and roll in quadrotor body is detected by gyro sensor when flying is balanced by gyro sensor. Gyro sensor act as input that detect stabilization problem and input data will be sent to microcontroller to make new output for quadrotor.
