摘要： In a flow control device 100, a comparator 40 outputs a first control voltage Vref based on a comparison of an instruction value signal Vi1 of the flow volume and a signal Vi2 according to the sensor output signal Vs. A feedback current generator 30 generates a feedback current Ifb according to a difference between the sensor output signal Vs and a signal Vi2 according to the instruction value signal Vi1. A feedback voltage generator 50 is a resister. A feed forward current generator 20 generates a feed forward current Iff according to the instruction value signal Vi1. A synthesis unit 60 generates a second control voltage Vdrv* obtained by adding to the feedback voltage Vfb a voltage according to a sum of the feedback current Ifb and the feed forward current Iff. The valve unit 90 is controlled according to the first and the second control voltage Vref, Vdrv*.
