| Abstract: | In order to improve the efficiency and accuracy of fault test and diagnosis on autopilot, a method based on the genetic algorithm was put forward to analysis the testability of autopilot. This method solved the problem on how to make genetic algorithm apply to the selection of test items, and could get the best fault test strategy. The strategy could finish test in the shortest time and meet the requirement of test coverage. Then the knowledge got from fault test could be used to simplify the dependency matrix between failure and test, so the diagnosis speed was increased. Finally a method which was combination of fault test and diagnosis was got. The experiment result shows that the method can increase the speed of fault test and diagnosis. At the same time, the method is easy to use. |
