To improve the deficiencies of the existing Min-Max controller for aero engines and to meet the requirements for Enhanced Engine Control, this paper proposes a control method based on the relaxation of limit values. This method aims to moderately loosen engine operating constraints to increase the response speed of the N1 during transient states. The fundamental idea is to slightly sacrifice the engine's operational safety by relaxing the engine's operating limits, thereby providing a faster engine response in emergency situations. Simulation results indicate that this method not only effectively accelerates the response speed of the N1 but also keeps the exceedance range of each limit protection parameter within an acceptable range.

摘要

To improve the deficiencies of the existing Min-Max controller for aero engines and to meet the requirements for Enhanced Engine Control, this paper proposes a control method based on the relaxation of limit values. This method aims to moderately loosen engine operating constraints to increase the response speed of the N1 during transient states. The fundamental idea is to slightly sacrifice the engine's operational safety by relaxing the engine's operating limits, thereby providing a faster engine response in emergency situations. Simulation results indicate that this method not only effectively accelerates the response speed of the N1 but also keeps the exceedance range of each limit protection parameter within an acceptable range.
