  • The concept of control method of the tracking camera of a rotary-wing aircraft based on the theory of fuzzy sets

    The basis of solving the problem of automatic takeoff and landing of helicopters is the problem of orientation of the aircraft relative to the landing site. Existing approaches are based on a combination of satellite positioning technology and sensors. Such solutions have a significant drawback - low positioning accuracy. In this regard, it is necessary to develop new methods that provide low computational complexity and high positioning accuracy relative to the landing site. The article provides an overview of modern solutions in the field of autonomous control of aircraft. The concept of a method for solving the problem of orientation of a helicopter relative to the landing pad is proposed. The approach is based on the use of a camera following the heliport sign. Determining the landing site is based on the theory of fuzzy sets and complex linguistic variables. Complex linguistic variables have three-dimensional membership functions, thus avoiding the problem of uncertainty. Simplification of the computational process is achieved through the use of projections of sections of three-dimensional membership functions.
