Title:
CONTROL DEVICE AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/008548
Kind Code:
A1
Abstract:
This control device performs calculation of an operation amount according to a PID calculation based on a program pattern for which a plurality of target values of a control object are set, and on a measurement value of the control object, the control device comprising: a partition boundary value setting unit 111 that sets as the partition boundary value a value that is between adjacent target values when a plurality of target values included in the program pattern are aligned in order of size; a storage unit 12 in which are stored PID constants corresponding to each partition determined by the partition boundary value; a PID constant selection unit 112 that determines to which of the partitions the measurement value of the control object corresponds, and selects the PID constant associated with that determined partition; and a PID calculation unit 114 that performs calculation processing of the operation amount by PID calculation using the PID constant selected by the PID constant selection unit 112.
