Abstract
A process controller includes a change fetch circuit for fetching a change in feedforward controlled variable due to a variation in load, and an auto-tuning control circuit for performing auto-tuning for mis-matching of the feedforward control, in accordance with a compensation variable obtained by multiplying a ratio of an adjusted output signal of a feedback control system corrected by the feedforward control to the feedforward controlled variable, with the change in feedforward controlled variable, to determine an optimal next feedforward controlled variable.
