Abstract: PROBLEM TO BE SOLVED: To provide a technology that facilitates design of control and easily obtains a flow rate by driving a motor on the basis of a deviation between a flow rate and its target value.SOLUTION: As a velocity value indicating a rotational velocity ω of a fluid feeding motor 4 that controls an air quantity Q, an estimate ω^ of the rotational velocity is adopted. As a torque value indicating torque T of the motor 4, an estimate T^ of the torque is adopted. The estimate ω^ is calculated from a torque current Iγ and a command value ωref of the rotational velocity ω, and the estimate T^ is calculated from a primary magnetic flux φ0 and the torque current Iγ. An air quantity estimation section 13 calculates an estimate Q^ from the estimates ω^ and T^. A PI control section 12 generates a command value ωref from a deviation ΔQ between a command value Qref and the estimate Q^ of the air quantity Q under PI control, thereby grasping the command value as a velocity command generation section. An inverter control section 2 obtains a control signal G from the command value ωref. An inverter 3 that operates according to the control signal G, drives the motor 4.
