导弹控制系统的容错控制研究

为了提高导弹姿态控制系统的可靠性，防止由于传感器失效而引起导弹自毁，提出基于信号重构的容错控制方法．为了对姿态控制系统中的传感器进行信号重构，首先考虑弹体弹性振动的影响，分析了弹体弹性振动与姿态角之间的关系；然后分析了传感器输出信号之间的关系；最后，通过解析冗余方法，用正常工作的传感器输出信号重构出现故障的传感器的正常信号．仿真实验表明了该方法的有效性．

On Fault-tolerant Control of Missile Control Systems

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.
