Abstract:

A solution from the field of missile drive based on geometric methods for the orbit tracking for unmanned aircraft has been proposed. This solution is also defined as a side-like pure proportional trace. Using the virtual target concept, the orbit tracking problem is converted into a corner tracking problem. With the virtual goal moving on the orbit and the follower also takes the virtual goal to the tracking corner, the orbit tracking is achieved. The speed of the virtual target depends on the ratio of a fixed coat tracking distance determined by the designer with the distance to the followers. It is necessary to choose a row for the rule of law and to design a term of misconception. The referred error term is found by using the similarity of the angle of the collision and the problem of the coat tracking. Numerical comparison works are shown on two orbits, straight and curved. The impact of the different tracking stages and the tracking distance determined by the designer on the tracking performance has been discussed.
