以某型防空导弹为背景,在给定的初始条件下,为使弹道需用过载分布合理,研究设计了一种适合工程应用的修正比例导引规律.运用多变量控制理论LQR方法设计的自动驾驶仪模型和实际舵机模型进行了全弹道6DOF数字仿真.结果证明:在考虑导弹纵向加速度、导弹重力和目标机动等因素下所设计的BTT-90导弹的修正比例导引规律正确合理,比修正前脱靶量明显减小,导弹跟踪性能良好,在目标机动时也能稳定击中目标。

Under the background of a certain type of air defense missile, under the given initial conditions, in order to make the trajectory overload distribution reasonable, a modified proportional guidance law suitable for engineering application is designed and studied.Using the method of multivariable control theory LQR The full-trajectory 6DOF numerical simulation is carried out on the pilot model and the actual steering model.The results show that the corrected proportional navigation law of the BTT-90 missile designed under the consideration of longitudinal missile acceleration, missile gravity and target maneuver is correct and reasonable The miss distance before the amendment is obviously reduced, the missile tracking performance is good, and the target can be stably hit during the target maneuver.
