摘　　要：针对航空发动机动态过程中参数可能会超出其物理限制的问题,提出了基于调幅曲线的发动机参数限制器设计方法。在紧急状态下,通过改变控制模式,修改发动机参数保护的限制值,释放发动机的保护裕度,快速提升发动机性能。仿真结果表明,基于调幅曲线的参数限制方法可以有效地限制发动机参数,抑制发动机过渡态的超调和振荡,确保发动机动态过程的安全。应急控制系统可以短时间内使发动机推力增加11.8%,提高紧急状态下飞机安全性和机上人员的生存能力。For the problem that the parameters maybe exceed the physical limits in dynamic process of aero-engine,a design method for parameter-limiter of aero-engine based on modulating curve is proposed. The parameters of limiter are changed with control mode,and the engine performance is enhanced by constraint release in emergency situation. The simulation results show that the limitation rules can ensure the safe of the engine and inhibit overshoot and oscillation. Emergency control can provide an additional 11. 8% of the engine thrust and improve the survivability of the aircraft and personnel on plane.
