Regenerative braking control strategy optimisation based on hybrid power source and PSO

How to achieve optimal braking force distribution and improve regeneration efficiency are urgent problems to be solved. A battery/super-capacitor hybrid power source and particle swarm optimization-based control strategy of regenerative braking is designed, which fully considers braking stability and efficiency. The regenerative power is taken as the fitness function, the optimal electric braking force is used as the optimisation goal, to achieve the optimal distribution of the mechanical and electric braking forces of the front axle. A MATLAB/Simulink-AVL Cruise co-simulation model is established, and the simulation studies are carried out under the CLTC, FTP75, and NEDC cycle conditions. The results show the proposed regenerative braking control strategy can effectively improve energy regeneration efficiency while ensuring braking stability, which verifies the effectiveness of the designed scheme. The research results offer the reference for the design of control strategy of regenerative braking for electric vehicles. Copyright © 2023 Inderscience Enterprises Ltd.
