H-infinity Control Theory in Vehicle Diesel Fuel Injection Pump Control System Design

Diesel engine fuel pump servo regulator is a larger factor by changing the parameters of car. The control system uses solenoid coils to control the fuel regulator location of the overflow population. Containing linear servo solenoid coil is immersed in oil, with the temperature changes the viscosity of fuel oil also changed, so this control system for a larger parameter changes. In this paper, H
_∞
control theory is applied to diesel engine fuel pump regulator agencies, design the corresponding robust control system to overcome the impact of parameter changes.
