LiBRA provides an open-source implementation of realisation algorithms used for generating reduced-order state-space models. This work aims to develop real-time capable physics-informed models for deployment onto embedded hardware. LiiBRA provides capabilities in offline and online model creation, as well as a framework for lithium-ion degradation predictions. For more information on LiiBRA, and the computationally-informed discrete realisation algorithm (CI-DRA), please refer to the publication above.
Further examples are located in the "examples" directory. Please open an issue if you have requests or ideas for additional examples.
