摘要
针对现代战机向目标空域的导引过程,建立了载机与目标相对运动的数学模型。基于最优控制的相关理论,以导引的准确性和控制的经济性为性能指标,建立了飞机导引控制算法。该导引算法既考虑了导引的角度误差又考虑了目标线角速度误差,通过对所得到的导引算法进行仿真验证,表明所得到的导引算法具有较强的适应性,能够满足飞机的导引要求。
In accordance with the guidance procedure for modern fighter towards target airspace, this paper deals with a mathematic modal of the relative motion between fighter and target. Based on the correlation theory of optimizing control, a guidance arithmetic of plane, considering guidance angle error and the target line rotation speed error, is presented with the guidance veracity and economical control as performance indexes. The results of many simulations show the good adaptability of the guidance arithmetic, which is suitable for the guidance of aircraft.
