Model and discretization impact on oscillatory optimal control for a diesel-electric powertrain
A mean value engine model is used to study optimal control of a
diesel-electric powertrain. The resulting optimal controls are shown
to be highly oscillating for certain operating points, raising the
question whether this is an artifact of discretization, modeling
choices or a phenomenon available in real engines. Several model
extensions are investigated and their corresponding optimal control
trajectories are studied. It is shown that the oscillating controls
cannot be explained by the implemented extensions to the previously
published model, nor by the discretization, showing that for certain
operating points the optimal solution is periodic.
