Initial state evaluation algorithm using fuzzy Bellman method

The problem of UAV control along a predefined trajectory is a well know problem and there are several methods that could accomplish this task. However, adding final conditions that the UAV have to meet at the end of the trajectory makes this problem more difficult. In this article, the authors present a fuzzy based method that is not time consuming and can solve this problem. The algorithm for flying at low altitudes are aimed to ensure the maximum safety of the flight by considering only the acceleration values that are possible to achieve by the object. In particular, the article presents: flight trajectory over mountainous terrain, the structure of altitude control system, the structure of normal acceleration control system, exemplary calculations and an object with velocity equals, membership functions of angle of attack, solutions' illustration, flight path angle and pitch angle along the trajectory, the demanded and actual normal acceleration along the trajectory and flying object trajectory.
