Abstract: Model Predictive Control (MPC) can be an interesting concept for designing a power management strategy for Hybrid Electric Vehicles (HEVs) according to its capability of online optimisation by receiving current information from the powertrain and handling hard constraints on such problems. In this paper, a power management strategy for a power split plug-in HEV is proposed using the concept of MPC to evaluate the effectiveness of this method on minimising the fuel consumption of those vehicles. Also, the results are compared with dynamic programming.

Keywords: plug-in hybrid vehicles; power management; model predictive control; MPC; dynamic programming; fuel consumption; plug-in HEVs; hybrid electric vehicles; optimisation; vehicle design.
