Immune-neural networks model of aeroengine performance monitoring
Author(s): 
Pages: 1748-1752
Year: Issue:  9
Journal: JOURNAL OF AEROSPACE POWER

Keyword:  免疫神经网络航空发动机性能监控人工免疫系统;
Abstract: 提出了一种基于免疫神经网络的航空发动机性能监控与故障检测模型.利用人工免疫系统的识别机理,并结合人工神经网络,确定发动机性能偏离正常值的程度(异常度),实现发动机性能趋势的监控.该方法能够灵敏、准确地反映发动机整体性能的变化情况,提高发动机性能正常与否的识别率,并以此来发现发动机潜在早期故障,防止故障的扩大.通过对某型涡扇发动机进行监控,证明该方法确实有效.
