摘要： In accordance with an embodiment, a plant control apparatus includes a deviation calculation unit, a velocity-type PID calculation unit, a plurality of integral calculation units, a plurality of overwrite units, and an automatic balance unit. The deviation calculation unit calculates a deviation between a process value from a plant with operation terminals and a set value corresponding to a control object, and generates a deviation signal. The velocity-type PID calculation unit generates a velocity-type operation amount command signal corresponding to the deviation. The integral calculation units generate position command signals as defined operation terminal position command signals. The overwrite units generate additional position command signals to perform overwrite processing and newly define operation terminal position command signals. The automatic balance unit calculates a deviation between the defined operation terminal position command signals, corrects the operation amount command signal and supplies the corrected operation amount command signal.

摘要： A power generation complex plant has a control switch, an overall control unit and a steam bypass facility. The overall control unit determines that a desired steam volume has reached a limit value of the volume of steam to be generated by a steam generating facility. A steam bypass facility control unit adds a bias value B1 to a control command value V4 of the steam bypass facility to generate a new control command value V5 when the desired steam volume is determined to have reached the limit value. The steam bypass facility control unit then controls the volume and pressure of steam passing through the steam bypass facility on the basis of the new control command value V5 so that no switch of control may be made in the control switch.

摘要： This invention relates to a modulating controller for controlling two operation terminals, and more particularly to a device to suppress disturbance to a process when a control signal is switched or when a bias is set. This invention, in a modulating controller to control a process amount by the total of two operation terminals disposed in parallel, when either of two H/A station devices outputs a manual operation value, provides a device which outputs a value obtained by reducing the manual operation value from the control amount of the process amount to be controlled by the total of two operation terminals as the control operation signal to the other H/A station device and prepares a value almost same with the operation terminal control signal outputted by one H/A station device as the control operation signal for one H/A station device. And, this invention automatically controls the process amount by either of the two operation terminals disposed in parallel, and in the modulating controller making one side as the backup, one operation terminal control signal is always tracked to the control operation device when both operation terminals are manually operated. When switching the other operation terminal to the automatic operation, timing to switch the other operation terminal to the automatic operation and timing to release tracking are delayed. During which a device to switch the tracking signal to the output of the other operation terminal is disposed.
