Adaptive Fuzzy PID Controller applied to micro turbojet engine
Journal of Physics: Conference Series, 2021 Abstract Digital controllers are utilized for controlling modern gas turbine engines. Firstly, an identified discrete model is built for a micro turbojet engine (MTE) jet cat P200sx. Two controllers are designed, gain scheduling PID and adaptive fuzzy tuned PID controllers are presented in this paper.
