摘要
Abstract
An improved A*algorithm was proposed to plan the trajectory for Unmanned Aerial Vehicle for-mation in the paper. First the cost function was designed on the basis of fuel consumption,length of trajecto-ry,formation shape and dangers of targets while unmanned aerial vehicles were flying in formation. Then the A*algorithm was used by adding-weight to the evaluations of trajectory before or after the knot being ex-panded. As a result,the balance between trajectory optimization and computing time was found. Meanwhile the computing efficient was also improved by changing the method of deleting and adding knot in the open list. The simulation results show that the A* algorithm can plan optimized trajectories for unmanned aerial vehicles flying in formation quickly and efficiently.关键词
