5754 针对前部喷管控制型外层空间导弹拦截提出了改进型比例导引(proportional navigation,PN)导引律,在目标的加速度大小和方向都有不确定性的情况下能够以零脱靶量命中目标。 Aiming at the front of the nozzle type control of outer space missile interceptor is proposed modified proportional guidance (proportional navigation, PN) guidance law, the target size and direction of the acceleration are under the condition of uncertainty to zero miss-distance, from hitting their targets.
5755 与以往的PN导引律不同,改进型PN导引律增加了消除偏差的项,且比例系数是时变的。 Unlike previous PN guidance law, the modified PN guidance law increased eliminating deviation, and the proportion coefficient is time-varying.
5756 此外,针对拦截的初始条件不理想的情况,提出了一个过渡的导引律,在经过有限时间采用过渡的导引律之后能够使得运动变量满足改进型PN导引律的适用条件。 In addition, in the presence of intercepting initial condition is not ideal, proposed an interim guidance law, after finite time using the transition law allows variables to meet the modified PN guidance law applicable conditions.
5757 最后,通过仿真验证了所提出的算法的可行性。 Finally, the feasibility of the proposed algorithm is validated by computer simulation.
