Repetitive control method is well known for its high performances in feedback systems that are subject to periodic exogenous inputs. This paper reviews the development of continuous and discrete repetitive control based on time-delay internal model, finite-dimensional repetitive control, repetitive control methods for nonlinear systems, together with a number of typical applications. Finally, some open questions and research issues are discussed.
