摘要

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.

Abstract: By combining aero-engine control and fault diagnoses methods, the aero-engine fault-tolerant control system based on control mode switch was designed, including task-level mode and engine-level mode. In case of failure of the engine components, the task-level mode could change the control strategies and modes to recover or reduce the aero-engine performance. In case of failure of a control loop, the control strategies were switched to other fault-tolerant control loops according to fault conditions, so as to ensure that the aero-engine continues to work normally. Numerical simulation result shows, the designed fault-tolerant control system can recover the aero-engine performance in 100% in case of failure of the components in the process of steady state or accelerated. And the designed fault-tolerant control system can switch to the fan speed control loop smoothly in 3 seconds in case of failure of the compressor speed control loop.
