Beschreibung
Zusammenfassung:	A controller apparatus, of repetitive operation, in which a numerical error signal representing the deviation of a variable with respect to a desired reference value is developed for each operation, and which is provided with means to develop an output signal for its transmission to a control device, output signal that tends to reduce said error signal to zero, characterized by the combination of: a number of storage or memory means; barrier means for transferring a portion of said numerical error signal from some of said selected operations to said numerical memory means until an amount proportional to the integral of said error signal is established in them; and means for coupling said numerical means of memory to said means for developing an output signal, giving an output signal provided with a component capable of responding to the amount in said numerical memory means.
