Abstract
An i.e. engine fuel control system includes a main fuel control which controls fuel flow to the engine in accordance with one or more engine operating parameters. The operation of the fuel control can be modified by a roughness sensing circuit which produces a roughness signal output dependent on the magnitude of fluctuations of engine speed. This output is applied to an integrator which provides a limited authority trim signal to the fuel control in accordance with the time integral of the error between the roughness signal and a speed-dependent reference signal generated by a speed-shaping circuit.
