Design of an Improved Hybrid FTC for Faults in Aero-Engine Closed-Loop Control System by Xiaofeng Liu, Chenshuang Luo, Liuqi Xiong

“…Due to the aero-engines in a high temperature, pressure, and spool speed environment, the concurrent faults in actuator/sensor combined with degradation of the aero-engine could arise the problem of closed-loop instability during the flight. For this purpose, an improved hybrid fault-tolerant control (FTC) technique has been studied in this paper to deal with simultaneous failure of actuators and sensors associated with health parameters of the typical components’ degradation in aero-engines. …”
