Abstract

A gliding unmanned aerial vehicle (GUAV) is considered. This vehicle is equipped with a high-aspect ratio wing and pneumatic control actuators. These elements make the long-range gliding flight of the UAV possible. The GUAV is the newest type of aircraft with improved performance.

The problem of guidance onto moving targets is very topical. The paper considers the problem of guidance onto moving targets under the conditions of flying along the designated route. The route is defined by navigational guidepoints. The number of these points may vary. The paper suggests an algorithm for generation of the initial states sets for the GUAV with the purpose of fulfilling the given mission. This paper is the development of papers [4-7]. In contrast to [7] this paper suggests a modernized and improved algorithm for the generation of the initial states sets for the GUAV. This algorithm consists of several stages: the stage of determination of the possible states set for the target (the point where the target is situated); the stage of determination of the critical points within the previously defined target states set (the critical points are the points, which are hardest to attain for the GUAV under the given initial conditions); the stage of generation of the initial states set for the GUAV. In this case the generated initial states set would be created as the intersection of GUAV initial states sets for all of the chosen critical points.

The target states set can be geometrically represented as a circle for the case of constant target speed. This paper illustrates some special cases, for example, when the target speed is low. In this case the target states set would transform into a circle with small radius, which can be geometrically represented as a point.
