Autonomous Energy Management Strategy in the Intermediate Circuit of an Electric Hybrid Drive with a Supercapacitor

IET Electrical Systems in Transportation, Volume 2024, Issue 1, 2024.
Hybrid electric vehicles (HEVs) require the design of an energy management strategy (EMS). Many EMS are solved using different types of deterministic rules (rule‐based (RB)) or optimization‐based (OB) methods. The disadvantage of these strategies is that the primary energy flows in the drive are only solved “ex post,” when in principle, they cannot ...

An Example of Modelica–LabVIEW Communication Usage to Implement Hardware‐in‐the‐Loop Experiments

Scientific Programming, Volume 2024, Issue 1, 2024.
Modelica is a very powerful language to simulate a very large set of systems, including electrical, thermal, mechanical, fluidic, control, and has already been used very extensively for several purposes, as the several Modelica conferences testify. Despite of this large literature, no paper seems to be available regarding the use of Modelica for real ...
