Abstract
PURPOSE: To automatically assure optimum control at the time of either command changing or fixed value control by a process controller which automatically controls the pressure, temperature or other process variables of a plant.
CONSTITUTION: A controlled process 11 is provided with a detection terminal 12 for detecting the process variable and transmitting it to the process controller 14 and with an operation terminal 13 for applying an operated quantity received from the controller 14 to the process 11. The process controller 14 comprises a command storage unit 22 which is operated by an operator to set and retain a command for the controlled variable, a command change start instructing mechanism 23, a control mode discriminate/shift unit 15, a control calculation unit 19 and an operated quantity transmission unit 24. The control mode discriminate/shift unit 15 selects one of a fixed value control calculation unit 21 against disturbance and a command change time control calculation unit 20 of the control calculation unit 19.
