基于智能决策的火箭安控系统

Rocket safety control system based intelligent decision

火箭在飞行过程中经常发生各种故障,因此需要对其飞行状态进行监视、判断,及时有效地做出相应的安全控制决策。在分析原有火箭安控系统的基础上,针对火箭飞行的特点及不确定的规则知识,提出了基于智能决策的火箭安控系统。首先给出了集弹道数据处理和安全控制决策于一体的计算机决策支持系统模型;然后根据安控系统的特点,对安控知识进行分类,给出了安控系统知识不确定的表示方法,形成了相应的安控决策网络;最后以Visual C++6.0为开发平台,构建了安控推理决策模型,给出相应的推理流程。仿真实验表示,该方法能实时监测出火箭的飞行状态,对其进行有效的管理,为安控领域专家的最终决策提供支持。

Various unpredictable faults often occur when the rocket is on mission.It is very important that the safety control deci-sion is made in time and effectively according to judging and analyzing the fly parameters.Based on the current rocket safety control decision system and in view of the characteristics for rocket aviation and the rule knowledge uncertainty,a rocket safety control system based intelligent decision is proposed.At first the computer decision support system model based trajectory data processing and the safety control decision is given.Then,the uncertain knowledge representation is established according to the characteristics of the system,and the corresponding decision network is formed.At last taking visual C＋＋ 6.0 as the development platform,the safety reasoning decision model is constructed and the corresponding reasoning process is given.Simulation experiments show that the method can realtimely monitor and effectively control the rocket aviating status,which provides the final decision for the safety control experts.
