ABSTRACT:
Disclosed is an automatic anticipatory control system for controlling, by one common control quantity, a plurality of points of operation that can be changed over individually and arbitrarily between start and stop operations and between an automatic operation mode and a manual operation mode. The system includes a master controller for obtaining a control signal for each of the points of operation that are operating in the automatic operation mode, on the basis of the sum of biases of the points of operation that are operating in the automatic operation mode, the sum of loads to be borne by the points of operation that are operating in the automatic operation mode on the basis of the common control quantity and the number of the points of operation that are operating in the automatic operation mode; a plurality of sub-loop controllers each disposed for each of the points of operation and generating a driving control instruction for each point of operation on the basis of the control signal; and driving means for practically driving the corresponding points of operation on the basis of the driving control instruction of each sub-loop controller.
