针对三余度飞行控制计算机控制单元的重构与恢复策略进行研究。首先简要介绍了飞控计算机的余度架构; 通过自检测与互检测相结合的方法, 设计了控制单元的重构策略; 通过合理地筛选恢复数据, 制定恢复协议, 设计了控制单元的恢复策略;最后搭建半物理仿真平台, 验证了重构与恢复策略的有效性和正确性, 提高了三余度飞行控制计算机的可靠性。
The reconstruction and recovery strategies aiming at the control units of the triple-redundancy flight control computer are studied. The redundancy architecture of the flight control computer is briefly introduced. The reconstruction strategy of the control unit is designed by combining self-detection with mutual detection. And then, the recovery strategy of the control unit is designed by reasonably screening the recovery data and formulating the recovery protocol. Finally, a semi-physical simulation platform is built to verify the validity and correctness of the reconstruction and recovery strategies, which improves the reliability of the triple-redundancy flight control computer.
