摘　　要：<div style="text-align:justify;"> <span style="font-family:Verdana;">Iterative learning control is a controlling tool developed to overcome periodic disturbances acting on repetitive systems.

Disturbances acting on the load of the system w</span><span style="font-family:Verdana;">ere </span><span style="font-family:Verdana;">reported for the case of past error feedforward only which kept the investigation of the current error feedback as an open question. This paper develops </span><span style="font-family:Verdana;">a comparison between the past error feedforward and current error feedback schemes disturbance conditions in singular values. As a result, the conditions found highly support the use of the past error over the current error feedback.</span> </div><div style="text-align:justify;"> <span style="font-family:Verdana;">Iterative learning control is a controlling tool developed to overcome periodic disturbances acting on repetitive systems.
