航空发动机主动稳定控制方法分析

Analysis of Aircraft Engine Active Stability Control Method

摘要:

主动稳定控制能够抑制压气机旋转失速、避免喘振,从而减小稳定裕度,扩大工作范围,使压气机性能得到最大发挥。针对航空发动机主动稳定控制关键技术,重点分析了以Moore-Greitzer模型为基础的压气机建模方法、模态控制与非线性控制两种主动控制方法,在此分析基础上,讨论了主动稳定控制算法存在的不足,并提出压气机模型与主动稳定控制算法的未来发展方向,可为航空发动机主动稳定控制理论研究与工程应用提供参考。

Abstract:

Active Stability Control(ASC) can suppress compressor rotating stall and avoid surge, consequently reduce stability margin, expand operating range and maximize compressor performance. Research progress is reviewed for ASC technology and its engineering applications. As ASC key technologies, the application limitation and developing trend of Moore-Greitzer-based compressor modeling method and the main active control method: modal control and nonlinear control were analyzed. the analysis may provide reference for compressor ASC theory research and engineering applications.
