Abstract: Abstract Feedback control systems can have reasonably good performance executing a desired trajectory, but only for frequencies up to the bandwidth of the control system. They never offer perfect tracking of an arbitrary desired trajectory. Repetitive control designs controllers to adjust the command to a feedback system aiming to converge to zero tracking error for any desired trajectory of a known period. It also aims to produce zero error in the presence of a periodic disturbance of known period. The ideal of zero tracking error is unusual in control and also challenging. This paper gives an overview of the methods preferred by the author to approach as closely as possible to this performance ideal.
