We aim to mitigate these shortcomings by developing data-driven models of such systems from the input\/output response data. We utilize tools from subspace identification, sparsity promoting regularization, and switching systems theory to determine the optimal time-varying data-driven models. Further, we develop Koopman operators\u2019 modeling techniques and extend them to control ESS.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"734\" height=\"742\" src=\"https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/image-7.png\" alt=\"\" class=\"wp-image-533\" srcset=\"https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/image-7.png 734w, https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/image-7-297x300.png 297w\" sizes=\"(max-width: 734px) 100vw, 734px\" \/><figcaption>Identifying Li-ion battery model from measurable input-output data<\/figcaption><\/figure>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/Sparse-Data-Driven-Modeling-of-LiBs.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of Embed of Sparse-Data-Driven-Modeling-of-LiBs..\"><\/object><a id=\"wp-block-file--media-1388ca0e-fee5-4483-8cb3-59e1bd0d1bd1\" href=\"https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/Sparse-Data-Driven-Modeling-of-LiBs.pdf\">Sparse-Data-Driven-Modeling-of-LiBs<\/a><a href=\"https:\/\/sites.temple.edu\/dslab\/files\/2022\/02\/Sparse-Data-Driven-Modeling-of-LiBs.pdf\" class=\"wp-block-file__button\" download aria-describedby=\"wp-block-file--media-1388ca0e-fee5-4483-8cb3-59e1bd0d1bd1\">Download<\/a><\/div>\n\n\n\n<p><strong>Publications:<\/strong><\/p>\n\n\n\n<p>Ahmadzadeh, O., Rodriguez, R., and&nbsp;Soudbakhsh, D. \u201cModelling of Li-ion Batteries for&nbsp;Real-Time Analysis: A Data-Driven Approach\u201d, American Control Conference, 2022.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Complex dynamical systems such as energy storage systems (ESS) have high-order models, which are costly to develop as they require the tedious task of determining the material and physical parameters of the system.
