Nowsheen Sharmili presented “Battery thermal management systems design considering model fidelity levels and design optimization utility” at the AIAA SciTech Forum 2024. [BibTeX] Abstract The electrification of transportation requires a robust and efficient design of battery thermal management systems (BTMSs). This study introduces a resistance-capacitance (RC) based reduced order model (ROM) with additional auxiliary state variables for accurately capturing transient thermal behavior. The study explores the trade-offs between model fidelity and utility in BTMS control co-design (CCD) applications. BTMSs manage …

A collaborative work on the CCD with a reduced-order horizontal-axis FOWT model is presented at the Wind Energy Science Conference 2021

April 4, 2024May 25, 2021

Publication Information Abstract Floating offshore wind turbine (FOWT) design involves many physics disciplines, including structural dynamics, aerodynamics, mooring system dynamics, hydrodynamics, and controls. In traditional engineering design practices, control design is generally left for a later stage of the design process, while plant design decisions, including geometrical shapes and sizes, are made with simple control assumptions. However, when there is a strong design coupling between plant and control designs, this sequential approach may not produce system-optimal solutions. To account for …
