由直流-交流逆变器和直流-直流变换器组成的电动汽车电力电子控制系统的发展引起了现代工业界的广泛关注。DC-AC逆变器为电动车辆的推进系统和公用事业负载提供大功率电机扭矩，而DC-DC转换器为传统的低功率和低电压负载提供电源。然而，在未来的电动汽车中对高功率双向DC-DC转换器的需求已经导致了许多新的DC-DC转换器拓扑的发展。功率变换器的非线性控制是电力电子领域的一个研究热点。本文重点研究了电动汽车用升降压型DC-DC变换器电源的模糊滑模控制策略。所提出的模糊控制器指定的表面和知识的表面变化的基础上的控制信号的变化，以满足滑模稳定性和吸引力的条件。所提出的模糊滑模控制器的性能相比，经典的滑模控制器。满意的仿真结果表明，所提出的控制律的有效性，减少了抖振现象。此外，所得到的结果证明了所提出的控制律对负载电阻和输入电压的变化在所研究的转换器的鲁棒性。
The development of electric vehicle power electronics system control, composed of DC-AC inverters and DC-DC converters, attract much research interest in the modern industry. A DC-AC inverter supplies the high-power motor torques of the propulsion system and utility loads of electric vehicles, whereas a DC-DC converter supplies the conventional low-power and low-voltage loads. However, the need for high-power bidirectional DC-DC converters in future electric vehicles has led to the development of many new topologies of DC-DC converters. The nonlinear control of power converters is an active research area in the field of power electronics. This paper focuses on the use of the fuzzy sliding mode strategy as a control strategy for buck-boost DC-DC converter power supplies in electric vehicles. The proposed fuzzy controller specifies changes in control signals based on the surface and knowledge on surface changes to satisfy the sliding mode stability and attraction conditions. The performance of the proposed fuzzy sliding controller is compared to that of the classical sliding mode controller. The satisfactory simulation results show the efficiency of the proposed control law, which reduces the chattering phenomenon. Moreover, the obtained results prove the robustness of the proposed control law against variations in load resistance and input voltage in the studied converter.
