A research on the optimal power distribution strategy for electro-mechanical drive

The mechanical and electrical power balance equations are formulated according to the split characteristic of power distribution unit and the merging characteristic of the power coupling mechanism in electro-mechanical drive. The multi-objective optimization model is established based on the optimal power distribution strategy, and a solving algorithm combining dynamic programming and dynamic prediction is put forward. The optimal control trajectories of engine and motors are obtained on the basis of comprehensive driving cycle and random electricity utility condition. The results of simulation verify the feasibility of the optimal power distribution strategy adopted, providing a basis for the formulation and optimization of real-time power distribution strategy.
