Regenerative braking can improve energy usage efficiency
and can prolong the driving distance of electric vehicles
(EVs). A creative regenerative braking system (RBS) is presented
in this paper. The RBS is adapted to brushless dc (BLDC) motor,
and it emphasizes on the distribution of the braking force, as
well as BLDC motor control. In this paper, BLDC motor control
utilizes the traditional proportional–integral–derivative (PID)
control, and the distribution of braking force adopts fuzzy logic
control. Because the fuzzy reasoning is slower than PID control,
the braking torque can be real-time controlled by PID control.
In comparison to other solutions, the new solution has better
performance in regard to realization, robustness, and efficiency.
Then, this paper presents the simulation results by analyzing
the battery state of charge, braking force, and dc bus current
under the environment of MATLAB and Simulink. The simulation
results show that the fuzzy logic and PID control can realize
the regenerative braking and can prolong the driving distance
of EVs under the condition of ensuring braking quality. At last,
it is verified that the proposed method is realizable for practical
implementation.
