| Abstract: | Based on statistical testing method of residuals or innovations such as Wald's SPRT criteria and the characteristics of neural networks,this paper proposes a new algorithm of fault detection for dynamic system,which is called intelligent decision algorithm. Because of relaxing the requirement on statistical properties of the systems,the algorithm has better robustness. The algorithm is applied to the fault detection for the liquid rocket engine with turbopump system,and simulation result shows that it is very effective. |
