基于模糊控制的电动车双向DC-DC变换器研究
Research on the Bi-Directional DC-DC Converter of the Electric Vehicle Based on the Fuzzy Control
摘要
Abstract
In order to prolong the driving range and the life cycle of the storage battery, ultracapcitor was used in this study as an auxiliary power source, the bi-directional DC-DC converter of the ultracapacitor was controlled to supplement the energy of the DC bus, and thus the efficiency of the electric vehicle power system was enhanced. Based on the dump energy of the storage battery and ultracapacitor and the need for load transient power, a method was proposed in this paper, in which a fuzzy controller was adopted to improve the performance of the bi-directional DC-DC converter of the electric vehicle. The fuzzy controller could automatically decide on proper output current according to different working conditions of the vehicle, and thereby control the current loop of the bi-directional half-bridge Buck/Boost converter. Simulation results proved that the control system was very dynamic, feasible and effective.关键词
