ABSTRACT:
A process for controlling a variable in respect of material in a series of interconnected vessels of a plant includes monitoring a variable in respect of each vessel. The monitored value of the variable is compared with a set point value of the variable. The differences between the monitored values and set point values of the variable resulting from at least one disturbance are summed. When such a disturbance in any one vessel results in a signal representative of the summed value being generated, each of a plurality of actuators of the plant are manipulated in a predetermined direction from the one vessel to cause rapid reduction of the disturbance. The invention extends to a control system for controlling a variable in respect of material in a series of interconnected vessels of a plant.
