Research on testability modeling of warship’s integrated electric propulsion system

As an important primary system of warship, the integrated electric propulsion system has higher requirements for its testability. Based on the theory of relevant model, this paper had provided a method of testability modeling for the warship, including building the product task model, relevant graphical model, relevant mathematical model and fault diagnosis tree. At the same time, the application research on testability modeling, test point optimization and fault diagnosis tree building of the warship’s integrated electric propulsion system was carried out, which had provided new ideas and means for improving the fault detection and diagnosis ability of warship’s integrated electric propulsion system.
