燃油约束下航迹规划算法研究与仿真

现有航迹规划算法通常不能够综合路径规划过程中的多种约束因素,且很少考虑到推进系统的能力限制,致使规划出的航迹实际不可飞。针对该问题,提出了一种满足飞行器多种机动性约束条件的航迹规划算法。对飞行器在垂直面内的运动状态进行分析,在传统代价函数的基础上提出了以燃油消耗为优化目标的代价函数。仿真结果表明,改进的代价函数能够对航迹进行很好的评价,所设计的规划算法搜索效率高,规划出的航迹实际可飞。

Research and Simulation of Path Planning Algorithm Under Fuel Oil Restraint

The existing path planning algorithm usually can not synthesize many kinds of limiting factors in process of path planning,and few considers the limit of propulsion system,which causes the flight path cannot be feasible.In view of this question,one new path planning algorithm that satisfies many kinds of mobility constraints of flight vehicle is proposed.Analyzed the flight vehicle’s state of motion in vertical plane,the cost function which optimized goal is fuel oil consumption in the foundation of the tradition cost function is put forward.The simulation result indicates that the improvement cost function can value the flight path well,the designed planning algorithm search efficiency is high,the planned path can be applicable.
