PROBLEM TO BE SOLVED: To provide a fluid coating system and a fluid coating method in which a response delay in a discharge amount can be suppressed upon varying the discharge amount per unit time from a nozzle.SOLUTION: In a fluid coating system which comprises a coating device which discharges fluid to a workpiece, moving means which moves relatively the coating device and the workpiece, and control means which controls the coating device, when the control means varies a discharge amount of a nozzle by a target variation amount F1 through adjustment of output of drive means (motor rotation number), the output of the drive means is set once as a value exceeding a theoretical output N1 of the drive means which is determined from the target variation amount F1 of the discharge amount and, thereafter, is set as the theoretical output N1, so that a variation amount of the inner pressure of the nozzle becomes a variation amount P1 by which the inner pressure of the nozzle determined from the target variation amount F1 of the discharge amount should be varied, to control the variation amount of the discharge amount to the target variation amount F1. 【課題】ノズルからの単位時間当たりの吐出量を変動させる際に吐出量の応答遅れを抑制できる流体塗布システムおよび流体塗布方法を提供する。【解決手段】ワークに流体を吐出する塗布装置と、その塗布装置とワークとを相対的に移動させる移動手段と、塗布装置を制御する制御手段とを備えた流体塗布システムであって、制御手段が、駆動手段の出力（モーターの回転数）を調整することによりノズルの吐出量を目標変動量Ｆ１だけ変動させる際に、ノズルの内圧力の変化量が、吐出量の目標変動量Ｆ１から求まるノズルの内圧力が変化すべき量Ｐ１となるように、駆動手段の出力を、吐出量の目標変動量Ｆ１から求まる駆動手段の理論上の出力Ｎ１を一旦超える値とした後で理論上の出力Ｎ１とし、吐出量の変動量を目標変動量Ｆ１に制御する。【選択図】図７
