摘要
PURPOSE: An IMU(Inertial Measurement Unit) for measuring redundancy of a sensor and detecting and isolating a failure by using a two-axis Gyro is provided to obtain an FDI(Failure Detection and Isolation) function by arranging three 2-DOF dynamically tuned Gyros to the particular direction. CONSTITUTION: An IMU for measuring redundancy of a sensor and detecting and isolating a failure by using a two-axis Gyro includes a first to a third acceleration sensor(11,12,13) and a first to a third 2-DOF dynamically tuned Gyro(21,22,23), and a sensor block(30). The sensor block(30) is used for fixing the first to the third acceleration sensors(11,12,13) and the first to the third 2-DOF dynamically tuned Gyros(21,22,23). Input sides of the first to the third 2-DOF dynamically tuned Gyros are symmetrically arranged to form a gradient of 45 degrees to a moving reference axis of a flying object in order to obtain 4 gyro inputs for each moving reference axis.
