复杂路径约束下巡飞弹侧向航迹规划方法研究

Research on lateral trajectory planning method of loitering missile under complex path constraints

提出了一种基于空天飞行器侧向制导逻辑的航迹快速规划方法。以预设航迹点和禁飞区为路径约束,基于粒子群算法设计的速度倾斜角反转策略消除了航迹点横程偏差;针对禁飞区约束,参考空天飞行器禁飞区规避策略,设计航迹偏航走廊,实现禁飞区规避。仿真结果表明设计方法能够保证航迹通过预设航迹点并规避禁飞区,验证了方法的有效性。

An air-to-space vehicle is proposed for the rapid trajectory planning of a loitering missile under complex path constraints.With the path constraints of preset track point and no-fly zone,the velocity tilt angle inversion strategy based on particle swarm algorithm is designed to eliminate the deviation of track point traverse for the track point constraint,and for the no-fly zone constraint,the track yaw corridor is designed with reference to the no-fly zone avoidance strategy of the air vehicle to achieve the no-fly zone avoidance.The simulation results show that the design method can ensure the trajectory to pass the preset track point and avoid the no-fly zone,which verifies the effectiveness of the method and takes less time.
