摘　　要：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。A Modified proportional guidance Law is studied and designed base on a certain antiaircraft missile here. The autopilot model designed by means of LQR method in multirariable control theory and actual vane actuator model arc simulated by the 6DOF numerical simulations of overall trajectory. The results show that the modified proportional guidance law designed for BTT-90 missile is correct, only if considering missile longitudinal acceleration, missile gravitation and target maneuvering. Compared with the unmodified guidance law, missdistance is obviously reduced, and the tracking performances have been improved.
