Abstract
Repetitive control is useful if periodic disturbances or setpoints act on a control system. Perfect (asymptotic) disturbance rejection is achieved
if the period time is exactly known. The improved disturbance rejection at the periodic frequency and its harmonics is achieved at the expense
of a degraded system sensitivity at intermediate frequencies. A convex optimization problem is defined for the design of high-order repetitive
controllers, where a trade-off can be made between robustness for changes in the period time and for reduction of the error spectrum in-between
the harmonic frequencies. The high-order repetitive control algorithms are successfully applied in experiments with the tracking control of a
CD-player system.
