A discussion covers control instability and aim target in nonlinear iterate systems with negative feedback method which based on Lyapunov stable theory.
本文从Ｌｙａｐｏｎｕｖ稳定性理论出发，利用负反馈方法来讨论非线性迭代系统的失稳控制与目标瞄准，并给出选择控制系数和有效控制范围的方法。
External force was used to control instability and aim target at nonlinear system.
利用外力法对非线性系统进行失稳控制与目标瞄准，根据Ｌｙａｐｕｎｏｖ稳定性理论选取控制系数，确定有效控制范围，对抵抗噪声干扰的能力作了理论分析。
The fall point coordinates of steel balls and the destroying center coordinates are calculated out,and the distributing figure of lethal elements is plotted,then we find that there is deviation obviously between destroying center and target aiming point.
通过合理假设,在解爆坐标系下建立了杀爆弹解爆后抛出的球形杀伤元素——钢珠的运动参数计算模型,解算杀伤元素弹道获得落点坐标和毁伤中心坐标,绘制落点散布图,发现杀伤元素毁伤中心与目标瞄准点有明显偏移。
