Abstract
A fuel supply system for an internal combustion engine includes a pump having a control member movable by an actuator. The actuator is powered by an amplifier which receives a control signal from an operational amplifier. One input of the opertional amplifier is connected to a summing junction to which signals representing speed demand, actual speed and control rod position are supplied by three transducers. The signal from the transducer which indicates the control rod position passes by way a circuit means which ensures that a derivative of the signal is applied to the summing junction.
