摘要：AbstractIn this paper, we proposed a hierarchical model predictive control (H-MPC) strategy to optimize the efficiency of the polymer electrolyte membrane fuel cell (PEMFC) hybrid electric vehicles (HEV). A linearized control oriented FCHEV model is presented first. Then, we construct the H-MPC strategy control scheme, consisting of an upper and a lower-level MPC controller. The upper-level MPC controller is designed to optimize the power splitting ratio (PSR) between the PEMFC and battery pack, while the lower-level controller is used to realize the tracking of maximum PEMFC net output power, via optimizing the oxygen excessive ratio (OER). A convex polyhedral set is used as a constraint in the lower-level MPC controller to guaranty the safe operation of the compressor. The US06 driving cycle is adopted to evaluate the performance of the proposed method, and up to 7.79% equivalent fuel consumption is expected.
