Abstract

PURPOSE: To obtain a low-cost process controller by giving sampling to the control amount given from the control subject and then calculating the new mean value based on the control amount and the mean value of the preceding control amount is order to deliver the operation amount in accordance with the target value and the deviation.
CONSTITUTION: The sampling is given to the control amount sent from control subject 1 through sampling unit 2 and by the command of operation control unit 5. Unit 5 receives the control amount sampled at unit 2 to calculate the new mean value based on the control amount and the mean value at the preceding sampling time point, and then decides the operation amount according to the deviation between the mean value and the target value based on, for example, the proportional integration control to then deliver the operation amount of subject 1. This damping action is repeated until the coincidence is obtained between the control amount and the target value. As a result, the memory device can be omitted, thus securing a low-cost constitution with the increased accuracy.
