Power flow split strategy for hybrid vehicles based on generalized predictive control

A new power flow split strategy for hybrid vehicles based on generalized predictive control (GPC) is presented. A velocity tracking problem, together with the minimization of fuel consumption and constraints in batteries state of charge and power sources limits, is solved without requiring any a priori knowledge of power use. To allow real-time computation, the proposed strategy uses simplified models of a diesel-electric hybrid vehicle. Simulation results are presented that confirm good performance of the strategy for three different driving cycles.
