Abstract
To enhance the reliability of missile attitude control systems and prevent the self-destruction caused by failed inertia sensors, an approach of fault-tolerant control based on signal reconfiguration is proposed. To reconfigure signals of the sensors in the missile attitude control system, the impact of elastic oscillation of the missile body is considered, and the relationship between the elastic oscillation of the missile body and the attitude angles is analyzed. The relationship among the sensors is also analyzed. The normal signal of a failed sensor is reconfigured with other normally working sensors via analytical redundancy. The simulation result shows the effectiveness of the approach.
