摘　　要：为优化飞机配电系统的供电模式转换过程,缩短因故障引起的汇流条断电时间,提出了一种飞机配电系统的快速时序逻辑控制方法,通过优化供电模式转换的触发事件,实现配电系统中关联接触器动作的预判断,完成配电系统时序逻辑的快速控制。通过基于有限状态机的仿真实验,表明本文提出的方法可显著地缩短供电模式转换时间,优化配电系统重构过程,保障飞机电源系统的高效可靠工作。In order to optimize the power supply mode conversion process of aircraft distribution system and shorten the bus power interruption caused by faults,a fast sequential logic control method for aircraft distribution system is proposed.By optimizing the triggering events of power supply mode conversion,the pre-judgment for the action of associated contactors in the distribution system is realized and the fast control of distribution system can be completed.Simulation experiments based on the finite state machine indicate that the method proposed in this paper can significantly reduce the transition time of the power supply mode conversion and optimize the reconfiguration process of the distribution system,which guarantees the efficient and reliable operation of the aircraft power system.
