摘要
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.
