| 摘 要： | 为了解决退化程度不同而导致的双发推力不匹配问题,首先介绍基于发动机性能退化缓解控制的双发推力匹配控制系统(在发动机基准控制系统的基础上添加外围控制回路实现对推力的间接控制,并通过设定双发共同遵循的期望推力减少由于发动机退化程度不同造成的双发推力差异),之后对该系统所涉及的推力设定、参数估计、转速指令修正等关键技术进行研究,最后在MATLAB/Simulink环境下进行仿真验证,结果表明:该系统可以在发动机参数限制范围内合理地设定双发共同遵循的期望推力,减少推力差异,满足自动协调双发推力匹配的设计要求。

| Abstract: | Research of thrust asymmetry compensation control based on turbofan engine performance deterioration mitigating control (EPDMC) was conducted. An outer thrust loop based on nominal control system was investigated, which manipulates thrust indirectly and minimizes thrust asymmetry through setting expected thrust followed by twin engine. Then key technology including thrust setting, parameter estimation and speed command modification was introduced. Simulation performed under MATLAB/Simulink conditions indicates the feasibility of the thrust asymmetry compensation control system in automatic thrust synchronization. |
