Control Algorithm for Planning Path of Unmanned Aircraft

The dynamics model based on aeromodelling uses computer control technology and GPS positioning. The coverage and flying precision of unmanned aircraft can be increased greatly. Effective control of observation area is achieved. It takes lots of time to calculate the path points if traditional continuous path control algorithms are adopted. It is not conducive to real-time control of aircraft. Calculation is simplified while Bezier curves are used to calculate the planning path point, but it is difficult to produce expected target path. Calculating time is short and flight path is accurate if linear and circular interpolation devices which are commonly used in numerical control system are applied to the turning path control algorithm of aircraft. Effects of flying speed and angle of attack on the height of aircraft and flight course control are combined in this paper to explain the realization of turning path control algorithm. The results show that the algorithm is simple and path control is accurate. Finally, the rationality of the design is verified through flight test and photography of aerial view.
