在燃料电池混合动力汽车（FCHV）与超级电容器（SC）用作辅助源的混合，经典的SC转换器限制了电流跟踪性能，由于存在一个大的输入电感。这个问题的硬件解决方案包括使用交错转换器拓扑，其能够显著降低输入电感。为了优化交错转换器的使用，必须设计一种智能控制方案，以最大限度地提高电流跟踪的闭环性能。为此，我们设计了两个控制器：一个瞬态控制器和稳态控制器。第一个控制器是一个bang-bang控制器，它能使系统从初始状态快速过渡到参考点附近的某个封闭区域。第二个控制器是基于切换面设计的，保证了某个期望极限环的局部渐近稳定。所提出的控制方案的性能和鲁棒性进行了评估，通过仿真与分段恒定源和参考电流。性能也进行了评估的电池一样的超级电容器车辆使用城市驾驶循环。(C)2017年氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
In fuel cell hybrid vehicles (FCHV) with a supercapacitor (SC) used as auxiliary source of hybridization, classical SC converters limit the current tracking performance due to the presence of a large input inductance. A hardware solution to this issue consists in using an interleaved converter topology that enables considerably reducing the input inductance. To optimize interleaved converters usage, an intelligent control scheme that maximizes closed-loop performance in current tracking must be designed. For that purpose, we design two controllers: a transient-state controller and a steady-state one. The first controller is a bang-bang one that guaranties a fast transition from the initial condition to some closed region around the reference. The second controller ensures the local asymptotic stabilization of a certain desired limit cycle and is based on switching surfaces design. The proposed control scheme performances and robustness are evaluated through simulations with piece-wise constant source and reference current. Performances are also evaluated on a battery-like supercapacitor vehicle using an urban driving cycle. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
