Key Words:six-axis accelerometer gyroscope fault diagnosis restoration

Abstract:An investigation into the fault diagnosis of a six-axis accelerometer is of great significance because of the high reliability requirement in areas such as aerospace. The working principle and decoupling algorithm of a six-axis accelerometer are introduced. The six-axis accelerometer and the gyroscope form the measurement system and provide the basis for fault diagnosis and restoration by deriving force and deformation compatibility equations. Descartes three-dimensional coordinate system of fault diagnosis is put forward, which carries out the function of real-time diagnosis of the measurement system. In view of a specific fault case, restoration was performed by replacing fault data of a branch chain with correct data. A relevant experiment was carried out and the results confirm the effectiveness of the restoration.
