Abstract
This paper investigates the performance of a double actuator electronic fuel control unit, when installed on a gas turbine engine. The validated mathematical model of the unit is linked to a quasi-linear engine mathematical model. A combination of two operating modes of the unit is used to improve the fuel delivery characteristics. Acceleration and maximum speed governing of the engine are simulated. Two control strategies are investigated. In the first, the fuel flow rate and the engine speed are used as feedback signals. In the second, the N-Dot control, which eliminates the need for fuel flow feedback during engine acceleration, is studied.
