ABSTRACT:
A feedback control system for use in an electrostatographic apparatus capable of, by successive approximation, approaching a value of charge on an electrostatographic imaging surface which is in correct proportion to a reference voltage thereby to result in near zero circuit error. A predictor circuit samples, during a sample period, the reference voltage, the charge on the imaging surface and the output of a first, conventional feedback loop to produce a corrected reference voltage value for the loop. During the sample period, this corrected reference is stored in first memory while a second memory receives a constant input reference for feeding to the loop. At sample end, the constant input reference is disconnected from the second memory and the contents of the first memory are fed to the second memory thereby providing the corrected reference voltage to the loop. When the apparatus is operational and producing copies, the process repeats itself thereby keeping the charge level close to the reference ideal.
