蒙特卡洛法在火箭简控系统设计中的应用

建立了火箭弹道仿真模型。用蒙特卡洛法对简控火箭在无控条件下进行了模拟打靶。从其所有成功子样中统计出了火箭运动参数在主动段一系列时间点上的容许偏差。分别以上述时间点为起点，综合考虑运动参数偏差及其它随机偏差的影响，对落点散布进行了仿真分析。找出了合适的简控时间终点及其运动参数容许的偏差范围，为简控系统的设计提供了直接依据。

The Application of Monte-Carlo Method in Designing Simple Control System of Rocket

The ballistic simulation model is established for a rocket. A lot of simulation target practice of the rocket is done with Monte Carlo method to the rocket under none control condition. The allowable deviations of motion parameters of the rocket at a series of time points in the power flight phase are statistically counted from all success trajectories. By setting up motion parameters at above mentioned time points as initial conditions respectively, the dispersion of falling points to the ground is analysed by simulation regarding to the influence of motion parameter deviations and the other random deviations. The suitable simple control terminal point and its deviations of motion parameters are found out,which provide useful information for designing simple control system of the rocket.
