Application of optimal control theory to the HEV dynamic process based control method

Abstract

The control method for the HEV propulsion system based on the dynamic process is proposed. The optimal control theory module and its application to DPCM are introduced. Based on the theoretical analysis, the simulation results including the HEV driving torque and power, power distribution for the multi-energy-source powertrain, fuel consumption and equivalent fuel consumption, SOC and discharge current of the storage battery are acquired, which help to prove the feasibility and validity of the DPCM advanced by this paper.
