A Bilevel Optimal Control Method and Application to the Hybrid Electric Vehicle

Optimal Control Applications and Methods, Volume 46, Issue 3, Page 1104-1119, May/June 2025.
Schematic representation of the Macro‐Micro method. ABSTRACT In this article we present a new numerical method based on a bilevel decomposition of optimal control problems. A strong connection between the proposed method and the classical indirect multiple shooting method is shown in the regular case, thanks to a link between the Bellman's value ...
