摘　　要：研究了典型的涡扇发动机控制系统(通常包含转速控制、加减速控制与温度保护控制等功能)的稳定性问题,研究表明这是一类特殊的多回路切换控制系统,论文推导了其稳定性的充分条件:涡扇发动机多回路控制系统在各单个回路稳定并且控制回路连续切换条件下是稳定系统。The stability of the turbofan engine control loops （which commonly includes speed control, acceleration/deceleration control and temperature protection control） was researched in this paper. The research showed that the turbofan engine control system was a special multi-switch control loops. A sufficient condition was given that made multi-control loops for turbofan engine control system be stably switched through every stable control loop and continuous switching.
