ス調節器。[Claims for Utility Model Registration] A setting section for setting a proportionality constant, an integral constant, a set value that is a control target for an external control device, etc., and a detection amount from the control device, based on the set value and the ARW value. In a process controller equipped with an arithmetic control unit that calculates the manipulated variable for the control device by proportional-integral PI operation, the value at the time of stabilization of the manipulated variable obtained as a result of the previous proportional-integral control operation is used as the ARW value. A learning value storage unit that stores the ARW value as It is determined whether or not they match, and when the two match, an ARW value readout signal is sent to the learned value storage section, and when the two do not match, an ARW value readout signal is sent to the correlation storage section. A process regulator comprising a discriminator that outputs an output.
