摘要

接收时间：2021年7月21日至2021年9月30日接受时间：质子交换膜（PEM）是可再生能源发电中最常见的燃料电池之一。本文提出了DC/DC升压转换器的结构以提高能源效率，并设计了比例积分控制器与自适应滑模方法相结合的方法，以实现高输出功率和恒定输出电压。由于使用了自适应技术，该方法能够覆盖具有未知上限的不确定性影响，除了提高PEM的输出功率和电压质量外，还消除了永久跟踪误差，确保了闭环系统的稳定性。利用李雅普诺夫方法获得了闭环系统的稳定性，并在MATLAB环境中进行了仿真和比较，结果表明，在该方法下，系统性能最优，与现有方法相比具有较高的效率。

Improving the Output Power of PEM Fuel Cell with PI + ASM Combined Controller Designed for Boost Converter

Received: July 21-2021 Accepted: September 30-2021 Proton-exchange membrane (PEM) is one of the most common fuel cells for renewable energy generation. In this paper, the structure of DC/DC boost converter is presented to improve the energy efficiency and the combination of proportionalintegral controller with adaptive sliding mode method is designed to achieve high output power as well as constant output voltage. The proposed method has the ability to cover uncertainty effects with an unknown upper bound due to the use of adaptive technique and in addition to improving the quality of output power and voltage of the PEM, also eliminates permanent tracking error and ensures the stability of the closed loop system. The stability of the closed-loop system has been obtained using Lyapunov method and the simulation and comparison results in MATLAB environment show the optimal performance of the system under the proposed method and high efficiency compared to the existing methods.
