ABSTRACT:
A control system that includes repeatable run-out (RRO) compensation comprises a control module that determines an error of the control system. An RRO compensation module receives the error, determines a repeatable component of an output response of the control system based on the error and a plant model of the control system, and updates a target response of the control system based on the repeatable component of the output response.
