空地导弹的一种复合导引法

在空地导弹的导引律中,比例导引法与直接导引法各有优缺点。针对它们的不足,提出了一种复合导引法。在推导过程中,应用了最优控制理论,使所得导引律不仅在控制精度方面最优,而且耗能最小。最后的分析表明,所提出的复合导引法充分结合了比例导引法与直接导引法的优点,在工程应用中有一定的价值。

A Combined Guidance Method for the Air-to-Ground Missile

Among the guidance principles of the air-to-ground missile, the proportional guidance method and the direct guidance method have their respective advantages and disadvantages. To overcome their shortages, a combined guidance method is presented. In the process of its development, the optimal control theory is applied, which leads to an optimal control accuracy of the concluded guidance principle and also the least energy consumption. The analysis at the end of this paper indicates that the combined guidance method fully integrates the virtues of both the proportional guidance method and the direct guidance method, and has practical values in the engineering applications.
