【摘要】 利用非线性奇异摄动系统两点约束最优问题的结论,在分析导弹质心运动方程两时间尺度特性的基础上,引用了一种闭环形式的奇异摄动最优中制导律的设计方法,详细分析了它的工程可实现性,最后将此方法应用于高超音速巡航导弹上,进行了三维弹道仿真,取得了良好的结果。在中制导结束时,能够保证导弹可靠地截获目标,顺利进入末制导段,证明了高超音速巡航导弹应用这种奇异摄动最优中制导律是可行的,可靠的。更多还原

【Abstract】 Taking the advantage of the conclusion on the most excellent problem of two restrains in the nonlinear singular disturbance system,through analyzing the two-time-scale behavior of point-mass equation for missiles,the paper puts forward a closed loop’s design method of singular disturbance’s optimum middle control law,and then analyzes its project feasibility in detail. Finally this method is applied to a high supersonic cruise missile to imitate the three dimension trajectory,which receives a good result.At the end of middle control,this method can ensure the missile to capture the target reliably,and come into the terminal control smoothly. All of these prove that it is feasible and dependable to apply the singular disturbance’s optimum middle control law to hypersonic cruise missile.更多还原
