Hydrogen associated with Proton Exchange Membrane Fuel Cell (PEMFC) as the prime candidate energy is becoming attention in transportation. However, the cost and the service lifespan are the main reasons that limit PEMFC wide application. In this paper, the super-twisting sliding mode (STSM) controller is designed for a four-phase interleaved boost converter (IBC) coupled with a PEMFC. The proposed controller can enhance the robustness of the output voltage while reducing the PEMFC current overshoot as much as possible for protection under a certain limitation of the PEMFC current ripple. The stability of the proposed controller is proved by the Lyapunov theorem. A typical proportional-integral (PI) controller based on ac small-signal model is designed for further comparison and discussion. The effectiveness of the STSM controller is further evaluated through experimental results obtained with a 1 kW fuel cell system based on a real-time hardware-in-the-loop system.

与作为主要候选能源的质子交换膜燃料电池 (PEMFC) 相关的氢正在成为交通领域的关注焦点。然而，成本和使用寿命是限制 PEMFC 广泛应用的主要原因。在本文中，超扭曲滑模 (STSM) 控制器是为与 PEMFC 耦合的四相交错升压转换器 (IBC) 设计的。所提出的控制器可以增强输出电压的鲁棒性，同时尽可能减少 PEMFC 电流过冲，以在 PEMFC 电流纹波的一定限制下进行保护。所提出的控制器的稳定性由李雅普诺夫定理证明。设计了一个基于交流小信号模型的典型比例积分 (PI) 控制器，以供进一步比较和讨论。
