针对火箭飞行过程和测量环境的复杂性及飞行特点的先验知识和规则的不确定性,提出了一个基于不确定推理算法的火箭安全控制方案。根据安判参数的特点,对其进行了分类,给出了专家系统知识的不确定表示和处理方法,并且结合安控决策规则和决策过程的特征,对推理控制策略进行了分析,并对冲突消解策略、搜索策略提出了相应的算法,给出了不确定匹配原则和可行度的传递方法,构建了与/或决策网和基于规则的通用不确定推理模型。实验和仿真表明该系统能迅速准确的获取火箭发射的各种警情,大大提高了火箭飞行安全控制决策的可靠性和真实性,对火箭的飞行状态进行有效的管理。
Aiming at the complexity of rocket flight and the complexity of measurement environment and the priori knowledge of flight characteristics and the uncertainty of rules, a rocket safety control scheme based on uncertain inference algorithm is proposed. According to the characteristics of security parameters, it is classified, and the uncertainty representation and processing method of expert system knowledge are given. Based on the security control decision rules and decision-making process characteristics, the inference control strategies are analyzed and the conflicts Digestion strategy and search strategy. Some methods are given to deal with the principle of uncertain matching and the feasible method of delivery, and the general uncertain decision model of decision-making network and rule-based is built. Experiments and simulations show that the system can quickly and accurately obtain various warnings of rocket launching, greatly improve the reliability and authenticity of rocket flight safety control decisions and effectively manage the rocket flight status.
