PROBLEM TO BE SOLVED: To provide a control apparatus for a fuel pump motor capable of controlling the motor with high responsiveness with a simple configuration.SOLUTION: A control apparatus for a fuel pump motor 100 comprises: a target voltage computing unit 101 for converting a command duty signal for driving the fuel pump motor into a target voltage applied to the fuel pump motor so as to supply a target quantity of fuel from a fuel pump; an FF control unit 104 for computing a feed-forward voltage on the basis of an amount of change in the target voltage; an I-control unit 106 for computing an integral voltage on a basis of the deviation between the voltage applied to the fuel pump motor and the target voltage; and an operation duty generation unit 111 for generating an operation duty signal for driving the fuel pump motor with the applied voltage by summing the feed-forward voltage and the integral voltage to obtain the applied voltage. |
