At the lower level, a linear controller stabilizes the open-loop process without considering the constraints. A higher-level controller commands reference signals at a lower sampling frequency so as to enforce linear constraints on the variables of the process. By optimally constraining the magnitude and the rate of variation of the reference signals applied to the lower control layer, we provide quantitative criteria for selecting the ratio between the sampling rates of the upper and lower layers to preserve closed-loop stability without violating the prescribed constraints. date: 2010-12 date_type: published publisher: IEEE place_of_pub: Hilton Atlanta Hotel, Atlanta, December 15-17, 2010 pagerange: 5216 -5221 event_title: Decision and Control (CDC), 2010 49th IEEE Conference on id_number: 10.1109/CDC.2010.5717405 refereed: TRUE isbn: 978-1-4244-7745-6 book_title: Decision and Control Conference official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5717405&isnumber=5716927 funders: This work was supported by the European Commission under project “WIDE - Decentralized and Wireless Control of Large-Scale Systems”, contract number FP7-IST-224168. projects: project “WIDE - Decentralized and Wireless Control of Large-Scale Systems” citation: Barcelli, Davide and Bemporad, Alberto and Ripaccioli, Giulio Hierarchical multi-rate control design for constrained linear systems.
