Fuzzy Adaptive Speed Controller for a Small Turbojet Engine

The paper presents a comprehensive approach in design of an intelligent controller usable for small turbojet engines. The controller has been designed using a complex non-linear model of a small turbojet engine, which incorporates its dynamics dependent on velocity and altitude. The main contribution of the paper lies in the design of an adaptive fuzzy controller with a very small rule-base that is usable for control of small turbine engines under all standard operating conditions. The paper represents proof of concept that a very simple to implement, yet effective fuzzy adaptive algorithm performs on par with other more complex approaches. The adaptive controller uses the developed parametric estimation of the engine's main parameters and has been validated in simulation environment and compared to other adaptive methodologies.
