Fault tree diagnosis method in flight control system combined with Bayesian
结合贝叶斯理论的故障树模糊故障诊断方法研究

The complexity of aircraft ground maintenance always causes the blindness and low efficiency of ground crew during the debug process in flight service.For solving this problem,a method of the fuzzy fault diagnosis expert system based on fault tree theory was proposed.By using Bayes' theorem to modify fuzzy relation formula,the quantitative relation equation was got and the decision-making step was given.Through the simulation,a flight control example was given and satisfying results were got.
