Dynamic modeling and optimal control for hybrid electric vehicle drivetrain

In this paper, the series-parallel drivetrain architecture present in Hybrid Electric Vehicles is studied and modeled in detail using Matlab/Simulink. The system is composed of two permanent magnet synchronous machines in addition to the internal combustion engine all mechanically combined using a power split device. The novelty of this model is to use exclusively basic Simulink blocks resulting in a less execution time especially advantageous during implementation. Furthermore, the new modeling approach is focused on optimal control of both engine and electric machines in wide speed region. The obtained simulation results are proving the accuracy of the simpler dynamic model and the efficiency of its control.
