Abstract: Quadrotor is one type of UAV (Unmanned Aerial Vehicle) which has considerable complexity in the regulation stability. This condition causes quadrotor requires a control system capable of keeping it stable. The quadrotor can do a Vertical Take-Off and Landing (VTOL), so it does not require a large runway for take-off and landing. That is one of the advantages compared to fixed wing aircraft. However, this VTOL capability requires good control. So, when quadrotor is taking off or landing, it still flies in a stable state without any interferences. These interferences make the quadrotor lose stability, undirected or fall. We can use several methods to control quadrotor. One of them is the control of the PID (Proportional control and Derivative). PID control system can work well depend on all three constants. The third tuning PID constants can be done independently by using fuzzy. The parameters of the self-tuning are the angle error and the difference in angle error that occurred during the flight.
