飞行器三维航迹规划算法

Three-Dimensional Path Planning for Aircraft

提出了一种应用改进遗传算法进行飞行器三维航迹规划的方法。航迹由B样条曲线得到,以代表航迹的B样条曲线的控制顶点坐标值作为染色体的基因位进行浮点数编码。在计算染色个体的适应值函数时充分考虑了飞行器的动力约束以及规避障碍能力。仿真结果表明了该方法的有效性。

This paper presents method for aircraft flight path planning in a three-dimensional(3-D) rough terrain by using improved genetic algorithm. The flight path is obtained by a B-spline curve whose control vertexes are considered as the genes of chromosome via floating point coding. Both the dynamic constraint and the ability eluding obstacles of aircraft are considered enough in the computation of fitness function. Results of simulation show the method is effective.
