Aircraft Inertial Measurement Unit Fault Diagnosis Based on Adaptive Two-Stage UKF

In the case of nonlinear systems with random bias, the Optimal Two-Stage Unscented Kalman Filter (OTSUKF) can obtain the optimal estimation of system state and bias. But it requires random bias to be accurately modeled, while it is always very difficult in actual situation because the aircraft is a...
