Application Number: JP,2023-100610
Category (FI): G05B11/32@C,G05B13/02@B
Stage: PROBLEM TO BE SOLVED: To shorten parameter adjustment time of a cascade control device.SOLUTION: A parameter adjustment device 3 adjusts a scaling lower limit and a scaling upper limit for calculating a target value RSP on a slave side in a cascade control device including a master-side control unit 1-1 and a slave-side control unit 1-2 from an operation amount MVm on a master side. The parameter adjustment device 3 comprises a parameter adjustment unit 31 which changes at least one of the scaling lower limit and the scaling upper limit until a controlled variable PVm is settled at a target value SPm based on a known slave-side controlled variable PVs=PVa when the controlled variable PVm is settled at the target value SPm and an operation amount MVm output from the master-side control unit 1-1 during cascade control when the controlled variable PVm is settled at a value different from the target value SPm during the cascade control.SELECTED DRAWING: Figure 1 (Grant)
