摘要
The transfer alignment of strapdown inertial units were proposed that use the H-infinity filter to estimate the misalignment of the slave INS (inertial navigation system) relative to the master INS. Characteristics of the H-infinity filter in transfer alignment were studied in detail by checking digital simulation results obtained by using the H-infinity and Kalman filters. The results shows that the misalignment angle obtained with the H-infinity filter converge faster and closer to the exact values than do those obtained with the Kalman filter. The H-infinity filter is more robust than the Kalman filter in transfer alignment for MEMS integrated navigation system.
