In order to improve and heighten the accuracy of condition trend analysis to key components of aircraft, to grasp their running state in time and avoid accidents, In the beginning, the paper analyze a lot of characteristic dates of running state from a large number of long-term tests deeply. On this basis, two condition trend analysis models: GM（1,1） and ARMA model are established, using these two models to analyze the condition trend of key components of aircraft, and operating the decision-level fusion of the results of the above models with D-S evidence theory. The research shows that both of GM（1, 1） model and ARMA model can predict the condition trend of key components of aircraft, and we can get the better result after using D-S evidence theory fusion. So this paper gives a good trend analysis method, and it has a good value of engineering application.

At present, life prediction for the aircraft key component is a widely recognized problem in the field of aerospace, especially the prediction precision. From the basic concepts and theory of fuzzy integral, this paper proposes a new method of life prediction which is based on information fusion theory. Firstly, BP neural network and RBF neural network are used to predict the remaining service life of the aircraft key component respectively. On this basis, fuzzy integral theory is used to conduct a decision-level fusion of the results to the above two neural networks. The experiment results show that the method of life prediction with fuzzy integral can realize the life prediction for the aircraft key component. The prediction precision is improved after information fusion. It has a wide application prospect and great practical value.

In order to improve the robustness and noise resistance of generalized minimum valance cothrol systems, several generalizedminimum variance control schemes are synthetically analyzed. The output variance caused by stochastic noise is decomposed to two parts. One part accords with the output variance of minboum vedance control and the other is the additional term of output variance causedby the control weighting factors. At the same time, the sensitivity function of modeling error is also deduced. A new robast design method that can minimize the sensitivity and the additional part of output variance is Presented by regulating variable parameters of contollers. The simulation results of self-tuning control show the effect of this method.
