Application of H-infinity design to automotive fuel control

An application of H-infinity robust design to a diesel fuel injection system is provided. The diesel control system must respond rapidly and accurately to the accelerator pedal even though the system encounters large parameter changes because of fluctuations in fuel velocity due to temperature variations. The resulting design is evaluated through computer simulation and laboratory experiments. The type-one robust control constructed by H-infinity design is shown to be much better than linear-quadratic optimal regulator design.<
