“…All above-mentioned strategies are formulated in time domain; however, the Spatial Repetitive Control (SRC) approach presented in Chen and Yang (2007) uses the angular position instead of time as the independent variable. The main idea behind spatial RC is that the disturbances generated in mechatronic systems are position dependent disturbances (those coming from eccentricities, axis unbalance, mass non-uniformity, coupling torques, etc.).…”

“…Estoúltimo presenta mayor complejidad matemática, pero permite fijar relaciones entre los valores máximos de la perturbaciones y la salida, i.e., entre sus normas L ∞ . Este enfoque puede relacionarse también con RC para sistemas en los que la periodicidad no es con el tiempo sinó con alguna de las variables de estado, lo que se ha dado en llamar spatial repetitive control (Chen and Yang, 2007;Yang and Chen, 2008).…”

El control repetitivo digital es una t´ecnica basada en el principio del modelo interno que permite seguir y/o rechazar se˜nales\ud peri´odicas. Una hip´otesis clave en los dise˜nos tradicionales de control repetitivo es que la frecuencia de tales se˜nales es constante y\ud conocida, siendo su principal desventaja la elevada degradaci´on de prestaciones que aparece cuando dicha frecuencia es incierta o\ud var´ıa con el tiempo. En este trabajo se presenta una revisi´on de las principales estrategias introducidas hasta la fecha para resolver este problema.Postprint (published version

“…In Steinbuch (2002), RC has been extended with robustness against small variations in the disturbance frequency, however large or continuous variations are not covered. Other existing approaches focus on defining the system in the spatial domain, resulting in a nonlinear system that requires an additional step of feedback linearization, see e.g., Chen and Yang (2007).…”

Motion systems are often subject to disturbances such as cogging, commutation errors, and imbalances, that vary with velocity and appear periodic in time for constant operating velocities. The aim of this paper is to develop a repetitive controller (RC) for disturbances that are not periodic in the time domain, yet occur due to an identical position-domain disturbance. A new spatial RC framework is developed, allowing to attenuate disturbances that are periodic in the position domain but manifest a-periodic in the time domain. A Gaussian process (GP) based memory is employed with a suitable periodic kernel that can effectively deal with the intermittent observations inherent to the position domain. A mechatronic example confirms the potential of the method.
