    • The invention prevents overshoot from occurring in flow rate on the output side of a flow rate regulator when output flow rate is changed or the gas type distributed is changed. Thus, an automatic pressure regulator is provided to supply gas pressure to a flow rate regulator that includes a piezoelectric element driving type pressure regulating valve, a control pressure detector provided on the output side of the pressure regulating valve, and a controller to which a detected value P2 of the control pressure detector and a set value Pst for control pressure are input, wherein the controller supplies a control signal to a piezoelectric element driving unit of the pressure regulating valve using a proportional control system to perform valve opening regulation, in which the proportional control system of the controller is set to control to bring about a residual deviation in control pressure by disabling an integral action.
    • 本发明防止了当流量改变或气体分布改变时流量调节器的输出侧的流量发生过冲。 因此,提供了一种自动压力调节器,用于向包括压电元件驱动型压力调节阀的流量调节器,设置在压力调节阀的输出侧的控制压力检测器和控制器提供气体压力, 输入控制压力检测器的值P2和用于控制压力的设定值Pst,其中控制器使用比例控制系统向压力调节阀的压电元件驱动单元提供控制信号,以执行阀开启调节,其中 控制器的比例控制系统设置为通过禁用积分作用来控制控制压力的残留偏差。
