摘要
从粗集的观点出发,将歼击机的损伤故障信息表示为一种信息系统,进而表示为决策表的形式,然后利用粗集方法对决策表进行属性简化,提取决策规则,再利用规则完成歼击机的损伤故障检测.粗集方法可直接处理歼击机的可测输出信号,不需要对象的数学模型和相关先验知识.仿真结果表明了所提出方法的有效性和实用性.
The information of aircraft's faults was denoted as a kind of information system based on rough set, and then as a decision table. Rough set based algorithms were applied to attributes reduction, rules extraction, fulfilling the detection of the damage faults. The proposed method dealt with measurable signal of the aircraft, mathematical model and no relevant transcendental knowledge was needed. The results of the simulation revealed the efficiency and practicality of this method.
