Filter with a time delay modeling for cascaded controller structure

摘要

A control system controls the movement of an object based on desired position data. The control system includes a first regulator configured to regulate the position of the object, a feed forward control configured to feed the desired position data forward to a second regulator at a lower level than the first regulator, and a modeling filter configured to receive the desired position data and to provide the desired position data to the first regulator with a predetermined time delay.
