Velocity-Free Attitude Fault-Tolerant Control
摘要
The analysis of recent spacecraft accident statistics shows that a significant portion of such is attributed to actuator fault for attitude control system [1]. In December 1983, faulty reaction wheels of satellite GPS BI-05 led to mission failure. A recent accident occurred with GPS BII-07, a spacecraft in the NAVSTAR GPS constellation developed by the U.S. Department of Defense. It suffered a reaction wheel failure that led to three-axis stabilization failure and a total loss of the spacecraft [2].
