Abstract: An electronic fuel control for a gas turbine engine comprises a manual control for setting the desired value of an engine parameter, an error amplifier connected to produce an error signal corresponding to the difference between the output of the control and an integrator, the output of the integrator controlling the supply of fuel to the engine. The error amplifier is connected to the integrator through a variable limiter, which applies a limit to the error in accordance with the difference between the integrator output and the actual value of the parameter. The limiter causes the error signal to go negative if this difference becomes too great.
