Aero-engine fault-tolerant control based on mode switch

  • 摘要: 综合了航空发动机控制和故障诊断方法,设计了基于模态切换的任务级和发动机级模式的容错控制系统.任务级模式在发动机部件故障时,通过切换控制策略和控制模式达到恢复或降低发动机性能的要求;发动机级模式在控制回路失效时,根据故障情况切换到容错控制回路,从而保证发动机继续正常工作.数字仿真结果表明:在稳态或加速过程中出现部件故障时,容错控制系统都能够100%恢复发动机的推力;在发动机中间、慢车和节流状态下,当压气机转速控制回路失效时,容错控制系统能够在3s内平稳切换到风扇转速控制回路.
