Switched Moving Boundary Modeling of Phase Change Thermal Energy Storage Systems

no code implementations28 Mar 2023 Trent J. Sakakini, Justin P. Koeln

Numerical simulations comparing the proposed approach with a more traditional FG approach show that the MB model is capable of accurately modeling the behavior of the FG model while using far fewer states, leading to five times faster simulations.

Hybrid zonotopes: a new set representation for reachability analysis of mixed logical dynamical systems

no code implementations28 Jun 2021 Trevor J. Bird, Herschel C. Pangborn, Neera Jain, Justin P. Koeln

This article presents a new set representation named the hybrid zonotope that is equivalent to the union of $2^N$ constrained zonotopes -- convex polytopes -- through the addition of $N$ binary zonotope factors.
