ABSTRACT:
A running control for a gas turbine engine includes a fuel control responsive to an input signal which corresponds to a desired rate of change of engine speed. A speed governor circuit generates a first output signal corresponding to a difference between demanded and actual speeds. Limit signal generators provide second and third signals which correspond to permitted acceleration and deceleration respectively. The second and third signals are integrated and a selected one of the first, second or third signals is applied to the fuel control. At least the integrator for the second signal can be reset by a feedback arrangement which modifies the integrator input in accordance with a difference between the desired rate of change of engine speed and the second signal.
