Título: | A supervisory control scheme for uncertain constrained time-delay discrete-time linear systems |
Autor: | Ahmadzadeh, Hamid Reza; Aghaei, Shahram; Puig, Vicenç CSIC ORCID | Fecha de publicación: | sep-2023 | Editor: | Elsevier | Citación: | Journal of the Franklin Institute 360(13): 10337-10364 (2023) | Resumen: | In this paper, a two-layer supervisory control scheme is proposed for discrete-time linear systems with state/input constraints, including multiple state time-delays, parametric uncertainties, and exogenous disturbance. The inner control layer is designed to achieve robust H tracking performance considering the delays as extra states but neglecting the input/state constraints. On the other hand, in the outer control layer, a command governor (CG) is designed to robustly guarantee the satisfaction of state and input constraints by computing a minimal Robust Positively Invariant (mRPI). To this end, the CG manipulates reference inputs by generating the nearest admissible value to be applied to the closed-loop system in both transient and steady-state response through the computation of the Maximal Output Admissible Set (MOAS). Finally, the validity of the proposed scheme is assessed in simulation using a numerical example and a continuous stirred tank reactor (CSTR) system. | Versión del editor: | http://dx.doi.org/10.1016/j.jfranklin.2023.07.025 | URI: | http://hdl.handle.net/10261/339432 | DOI: | 10.1016/j.jfranklin.2023.07.025 | Identificadores: | doi: 10.1016/j.jfranklin.2023.07.025 issn: 0016-0032 |
