Abstract | Links | BibTeX | Tags: Internal model principle, Output regulation, Sliding mode control @inproceedings{nokey, A dynamic state-feedback sliding-mode controller (SMC) based on the internal model principle (IMP) is proposed for the tracking of exogenous signals. The proposed SMC is robust to both matched disturbances and mismatched exogenous disturbances. It also achieves robustness to matched parametric uncertainties and a certain degree of mismatched parametric uncertainties. The stability of the closed-loop system and the existence of a global solution are theoretically guaranteed by a specific initialization of the internal model. Its performance is demonstrated through numerical simulations. |

Hyungbo Shim / Jung-Su Kim / Hongkeun Kim / Juhoon Back A note on the differential regulator equation for non-minimum phase linear systems with time-varying exosystems Journal Article In: Automatica, vol. 46, no. 3, pp. 605-609, 2010, ISSN: 0005-1098. Abstract | Links | BibTeX | Tags: Output regulation @article{ShimKimKimBack10, Some control problems in practice are often formulated as a linear output regulation problem with time-varying exosystems. Although this problem has been studied recently, an explicit and constructive solution has been given only for minimum phase systems. This paper presents a solution for non-minimum phase systems whose zero dynamics is hyperbolic (or has an exponentially dichotomic split in the case of time-varying zero dynamics). The idea is inspired by the non-causal stable inversion. |
