基于高斯伪谱法的枪榴弹制导算法

Gaussian Pseudo-spectral Method for Smart Grenade Guidance

针对目前枪榴弹制导算法稀少,传统中大口径弹药的制导方法不适用于枪榴弹制导等方面的问题,提出基于高斯伪谱法的枪榴弹制导算法。该算法利用高斯伪谱法规划出一条最优弹道作为标准弹道,依据实时弹道和标准弹道的偏差生成制导指令。以修正能量和制导精度为指标,对该算法进行仿真验证,结果表明该算法具有修正能量小、制导精度高的特点,易于在枪榴弹上实现与应用。

In response to the problems that the current grenade guidance algorithms are scarce and the traditional guidance methods for medium and large caliber ammunition were not applicable to grenade guidance,etc.,a grenade guidance algorithm based on Gaussian pseudo-spectral method was proposed.The algorithm used the Gaussian pseudo-spectral law to delineate an optimal trajectory as the standard trajectory,and generated guidance commands based on the deviation between the real-time trajectory and the standard trajectory.The algorithm simulation results were compared with those of the Gaussian pseudo-spectral-based guidance algorithm,the proportional guidance method and the drop-point prediction guidance method,and the results showed that the Gaussian pseudo-spectral based guidance algorithm in this paper had the characteristics of small correction energy and high guidance accuracy,and was easy to be implemented and applied to grenades.
