发动机紧急状态下快速响应控制研究

摘要

Modiifed acceleration schedule (MAS) and high speed idle (HSI) control which was applied in the process of fast response of engine dynamic were described. By modifying he parameters of the limiter in engine control system, release the acceleration constraint, satisfactory performance can be obtained through MAS. And HSI is by raising the speed of HP rotor in idling condition, decreases the acceleration time in emergence. Simulation results show that: settling time was shortened from 5.36s to 4.69s in the MAS control while reached 3.62s in HSI control.%文中介绍了两种在紧急状态下发动机快速响应控制的方法：调节加速度(MAS)控制和高速慢车(HSI)控制。MAS控制是修改发动机控制系统中限制器的参数值，释放发动机加速限制，从而获得理想的加速性能。HSI控制是提高发动机慢车状态时高压转子转速，在紧急状态下，大幅度缩短发动机的加速时间。仿真显示：采用MAS控制，发动机加速时间由原来的5.36s缩短至4.69s，而采用HSI控制，发动机的加速时间减小至3.82s。
