Abstract
Digital repetitive control is a technique which allows tracking periodic references and/or rejecting
periodic disturbances. Repetitive controllers are usually designed assuming a fixed fundamental
frequency for the signals to be tracked/rejected and its main drawback being a dramatic
performance decay when this frequency varies. A usual approach to overcome the problem
consists of an adaptive change of the sampling period according to the reference/disturbance
period variation. This paper presents a stability analysis of a digital repetitive controller working
under time-varying sampling period by means of an LMI gridding approach. Theoretical
developments are illustrated with experimental results, which are preceded by a detailed
description of fundamental issues related to the implementation procedure.
