针对使用传统Gauss伪谱法(GPM)求解航迹规划问题时计算复杂的问题,提出了基于两点间经纬度坐标变换的改进GPM高超声速飞行器滑翔段航迹规划方法。对经纬度坐标进行处理,以经纬度变换代替时域变换改进GPM,规划两点间的航迹。仿真结果表明,改进后的算法能够准确、高效地规划出一条合理的航迹,满足飞行约束条件。 Aiming at the problem of complex computation when solving the traditional trajectory planning problem by using the traditional Gauss pseudospectral method (GPM), a gliding path planning method based on the coordinate transformation between two latitude and longitude (GPM) is proposed. The latitude and longitude coordinates for processing, latitude and longitude transformation instead of time-domain transformation to improve the GPM, planning the trajectory between two points. The simulation results show that the improved algorithm can accurately and efficiently plan a reasonable track to meet the flight constraints.
