中文摘要 | 本文針對目標無閃躲且飛彈側向加速度受限制之條件下,推導並討論飛彈採純追逐式導引軌跡之正確解。在相同狀況下,文獻中之解法仍有不完整之處,本文將之補強,並求出正確解。正確解之求解係基於運用Buckingham Pi理論,從而獲得無因次參數,方得求出完整解。另相關重要性質如側向加速度需求、能量指標皆提出討論。最後將本文解法與傳統解法以模擬例證比較。 |
英文摘要 | The method and discussion for derived an exact trajectory with lateral acceleration constraint to the pure pursuit course are presented. The solutions obtained before under pursuit scheme seems incomplete. Now in this paper, the exact and complete solutions are derived for non-maneuvering target, which are more general and comprehensive than those obtained before. The exact solution is based on scaling theory with the Buckingham Pi theorem to determine the relationship among the non-dimensional parameters. Some related important characteristics, such as lateral acceleration demand and energy cost, are investigated and discussed. The exact solution for graph the trajectory of pursuit guidance are validated and compared with the classical method derived by Howe etc. |
