N2 - In view of that energy storage unit (ESU) in conventional series electric drive system results in the defects of large volume, high cost and low life span, a series electric drive system without ESU is proposed, and aiming at the issue of bus voltage fluctuation caused by ESU elimination, fuzzy control is added on the basis of traditional voltage/current dual closed-loop PI control, a DC bus voltage control strategy for fuzzy adaptive PI control is formulated and an online self-tuning scheme for PI parameters is put forward. A model for series electric drive system without ESU is established with Matlab/Simulink and a simulation is conducted on the model and control strategy. The simulation results show that the fuzzy adaptive PI control strategy is conducive to increasing the response speed of system, reducing voltage overshoot and enhancing the robustness of system with better static and dynamic performances.
