Abstract

The global energy evolution is at a critical juncture, necessitating an urgent transition towards clean and sustainable energy sources, notably green hydrogen, to combat climate change and the inevi-table depletion of fossil fuels. This transition is underscored by the emergence of fuel cell electric vehicles (FCEVs) as a promising solution for clean transportation, demanding advanced DC-DC power converter technologies to ensure their efficiency and reliability. This paper addresses the topic of control for the Quadratic Boost Converter, which presents a challenge due to its non-minimum phase characteristic and nonlinear nature. To tackle this, a nonlinear controller is developed using dual-loop control employing STA-SMC and Lyapunov theory as the control ap-proach. Simulation and experimental validation evaluate the controller's performance, testing ro-bustness against varying load currents and under time-varying reference voltages to assess its ef-fectiveness.

燃料电池电动汽车二次升压转换器高阶滑模控制的开发与实验验证

全球能源演变正处于一个关键时刻，迫切需要向清洁和可持续能源（尤其是绿色氢能）过渡，以应对气候变化和化石燃料不可避免的枯竭。燃料电池电动汽车（FCEV）的出现凸显了这一转变的重要性，它是清洁交通的一种有前途的解决方案，需要先进的直流-直流电源转换器技术来确保其效率和可靠性。本文探讨了二次升压转换器的控制问题，由于其非最小相位特性和非线性性质，该转换器的控制面临着挑战。为解决这一问题，本文采用 STA-SMC 和 Lyapunov 理论作为控制方法，利用双环控制开发了一种非线性控制器。仿真和实验验证评估了控制器的性能，测试了控制器在负载电流变化和参考电压时变情况下的稳定性，以评估其有效性。
