无人机双余度飞控系统余度管理策略

Redundancy Management Strategy for UAV Dual-redundancy Flight Control System(FCS)

针对无人机系统安全可靠性以及经济性的需求,对基于无人机的双余度飞控系统架构和工作方式进行了分析,研究了适用于无人机的双余度飞控系统信号监控表决策略,实现了双余度信号故障—安全的保障体系。与传统三余度或四余度飞控系统相比,基于双余度配置及监控策略的飞控系统具有结构更简洁、体积更小、重量更轻、经济性更好的特点,其安全可靠性满足中型或大型无人机系统研制需求。

With regard to the needs of safety,reliability and economy of the UAV system,this paper analyzes the UAV-based dual-redundancy FCS architecture and operation mode,studies the dual-redundancy FCS signal monitoring and voting strategy applicable to the UAV,by virtue of which a dual-redundancy signal failure-safe support system is achieved.Compared with the conventional triple-redundancy or quadruple-redundancy FCS,the FCS based on the dual-redundancy configuration and monitoring strategy is simpler in structure,smaller in size,lighter in weight and better in economy,and its safety and reliability meet the requirements for research and development of the medium and large-sized UAV systems.
