ABSTRACT:
A fuel system for an engine has a first summing amplifier to which are fed signals representing demanded and actual values of the output of a pump supplying fuel to the engine, together with a signal representing engine speed. The summing amplifier compares the signals it receives and produces an output controlling the output of the pump, and there is also a second summing amplifier to which are fed electrical signals representing engine speed and a reference, a discriminator coupling the two summing amplifiers to a means for controlling the pump, so that the output from the discriminator at any instant is the output from the amplifier demanding the least fuel.
