摘要

LLC谐振变换器以其低开关损耗和高功率密度的优点被广泛应用于电动汽车充电器中。但其动态性能和鲁棒性容易受到多种干扰因素的影响。为了提高LLC谐振变换器的动态性能和鲁棒性，提出了一种非奇异快速终端滑模控制策略。首先，根据扩展描述函数法建立的大信号数学模型进行线性化和简化，得到二阶小信号模型;然后，基于小信号模型设计了NFTSM控制器。并用李雅普诺夫稳定性定理证明了系统的稳定性。最后，仿真结果验证了所提控制方案的可行性和有效性。

Nonsingular Fast Terminal Sliding Mode Control of LLC Resonant Converter for EV Charger

LLC resonant converter is widely used in electric vehicle (EV) charger for the advantages of low switching loss and high power density. However, its dynamic performance and robustness are easily influenced by multiple disturbance factors. This paper proposes a nonsingular fast terminal sliding mode (NFTSM) control strategy for the LLC resonant converter to improve the dynamic performance and robustness. First, the second-order small-signal model is obtained by the linearized and simplified large-signal mathematical model which is established based on the extended description function method. Then, the NFTSM controller is designed based on the small-signal model. And the system stability is proved by Lyapunov's stability theorem. Finally, Simulation results verify the feasibility and effectiveness of the proposed control scheme.
