ANTICIPATORY ADAPTIVE CONTROL SYSTEM

摘要

A method and a device for an adaptive forward feeding of a disturbance correcting signal in a regulator is based on storing an output signal from the regulator at a first time point t0 corresponding to the occurrence of a disturbance. At a later time point t1 when the disturbance has been settled by the regulator, a second output signal from the regulator indicative of the final integration level is compared with a stored signal and the difference signal is processed and combined with a constant disturbance correcting signal, thus producing another an adapted disturbance correcting signal which minimizes the deviation from a desired magnitude and at the input of the regulator. The processing of the adaptive correction signal at the output of the comparator is preferably made by an integration according to a preset formula of a plurality of differences produced from a plurality of forward switching actions before the second time point t1. The averaged adaptive correction signal is then applied at the time point t1 to a summing device where it is added to the constant disturbance correcting signal.
