Design of Fault-tolerant Control Algorithm for Aeroengine Performance Degradation

For aeroengine performance degradation problems, this paper constructs a certain type of single axis aeroengine model, and introduces the concept of health parameters. Through the establishment of deviation index function designed in the face of aeroengine fault detection algorithm was proposed to performance decline at work, at the same time design based on rotating speed and health parameters double scheduling gain scheduling of PI controller, effectively improved the aeroengine decline in the performance of the control performance.
