| Abstract: | To improve the performance of real-time,in-time,and veracity in fault detection and diagnosis of liquid rocket engine（LRE）,the negative selection algorithm of artificial immune system was applied in this paper.The fault detection and diagnosis were carried out,while the artificial recognition ball（ARB） was constructed and the maximum similarity rule was adopted.The experiment was performed with steady state data collected in some ground test.The results showed that this method had the function of quickly detection,high rate of correction diagnosis,and powerful ability of discovering the unknown fault.It could be widely applied in the state monitoring and fault diagnosis of LRE. |
