The Helicopter has a lot of flight modes. The most characteristic flight mode is Hovering. It enables the helicopter to be used in many situations. However, a helicopter has nonlinear dynamics so its mathematical modeling is very difficult. So it is not easy to control helicopter in hover.
In this paper, RC model helicopter is selected as a plant which has more fast and more sensitive dynamics than real one. To stabilize the behavior of RC model helicopter in hovering mode, Fuzzy algorithm is used as a controller andone camera is used as a sensor. To get proper Information from camera Image, three characteristic points are attatched to the helicopter and a positiion recognition algoritem is developed.
Experiments are performed to stabilize 3 rotational motions sincronousely with fuzzy control algorithm. Compared to conventional PID control Fuzzy control represents better performance.
