Abstract

A pre-read learning digital servo-control device has a digital servo-control device for controlling the speed and/or position of a controlled object. A corrective control input for a (n+1)-th trial for state control is based on errors observed in the n-th trial. The corrective control input is applied at m sample time(s) before the time when a subsequent error is observed, where m is an integer greater than or equal to one for a sampling time of the digital servo-control device.
