Abstract: Perfect regulation may be too stringent a condition in repetitive control. In this paper, the rigid stability requirement is relaxed by including an appropriately chosen filter in the repetitive ...

Abstract: This paper considers the use of external models for the cancellation of disturbances that can be regarded as output of stable (in the sense of Lyapunov) autonomous systems. The external model ...

Abstract: Repetitive control is formulated and analyzed in the discrete-time domain. Sufficiency conditions for the asymptotic convergence of a class of repetitive controllers are given. The “plug-in” ...
