A controller 1 which controls fuel pressure Pf of a fuel supply system 10 includes an ECU 2. The ECU 2 sets a target fuel pressure Pf_cmd, calculates a first control input Rsld for causing the fuel pressure Pf to converge to the target fuel pressure Pf_cmd, with equations (1) to (6), modulates the first control input Rsld with equations (11) to (31) to thereby calculate a second control input Udsm, and depending on whether or not during fuel-cut operation or pressure decreasing control, selects one of the first and second control inputs Rsld and Udsm as the control input Upf.Field of SearchControl of air/fuel ratio or fuel injectionControlling timing Engine stop, fuel shutoff Specific memory or interfacing device Digital or programmed data processor Cylinder cut out Including means responsive to instantaneous change in engine speed Having perturbation Flow control (e.g., valve or pump control) | |
