An Effective Energy Management Strategy for Series-Parallel Hybrid Electric Vehicle using COOT bird Optimization Algorithm

Abstract

The lack of fossil fuels and greenhouse gases effects has motivated car manufactures to introduce new generation hybrid electric vehicles. In this paper the COOT optimization algorithm is employed to search optimal controller gains in Electric Vehicles. The objective of optimization is to attain fuel economy, subjected to vehicle constraint. The Vehicle power split is done in such a way that at every moment, the net power demand on final drive is fulfilled by either the internal combustion engine alone, the motor alone or in combination. This series-parallel HEV addressed in this paper, has complex configuration. The operation modes create complications in controller design. Therefore, a MATLAB based simulation study was carried, to check the feasibility of COOT optimization in the controller design. The obtained results from 4 different drive cycles, shows that the fuel consumption of vehicle can be reduced by the optimization of controller parameters.
