摘要: Engine model plays a critical role in many applications of gas turbine engine, especially for fault tolerant control and gas-path prognostic and health management. However, traditional pure physics-based modeling method has difficulty in dealing with engine-to-model mismatch, sensor measurement uncertainty, etc., leading to a big limitation in real applications. In this paper, a novel improved hybrid modeling (IHM) method is proposed to accurately model a dual spool turbofan gas turbine engine. The proposed IHM method is …
