)項記載のプロセス制御装置。[Scope of Claim for Utility Model Registration] (1) Setting means for setting either or both of the increase amount or decrease amount per unit time of the set value and the internal set value, and the detection signal and control from the startup start detection means When receiving a control cycle signal from the cycle signal generating means, a new internal set value is calculated based on the internal set value, the set value from the setting means, and an increase/decrease in the internal set value, using the internal set value as an initial value. an internal set value calculating means, a controlled variable detecting means at startup, a deviation detecting means for detecting a deviation between the controlled variable detected by the internal set value calculating means, and a control signal from the control cycle signal generating means for each control cycle. and control calculation means for performing control calculation based on the deviation from the deviation detection means and outputting a manipulated variable. (2) Set both the amount of increase and the amount of decrease, and when the internal set value is smaller than the set value, increase the slope determined by the increase amount until it matches the set value, and when the internal set value is greater than the set value The process control device according to claim 1, which is a utility model, and is characterized in that the process control device decreases the amount at a gradient determined by the amount of decrease until it matches a set value. (3) Set only the amount of increase, and if the internal set value is smaller than the set value, increase the gradient determined by the amount of increase until it matches the set value, and if the internal set value is greater than the set value, immediately change to the set value.
