。[Claims for Utility Model Registration] Multiple control devices installed in parallel allow one
A feedforward control device in a device that controls two control variables, wherein the control variation (PVi) handled by each of the parallel control devices is divided into the control variation (PVi) of the one control variable ( PVo); and a feed forward amount calculation circuit which inputs one control variable and sets the output from the division circuit as a gain via a switch. When a transient fluctuation occurs in a controlled variable, the switch is turned on, and the output of the feedforward amount calculation circuit is applied to the plurality of control devices to respectively correct the set values thereof. feed forward control device.
