基于扩张状态观测器的燃料电池DC-DC变换器控制

Due to the nonlinear volt-ampere characteristic of fuel cell (FC) stack, a dc-dc power converter is essential to be interfaced, to regulate a stiff dc bus to properly power the load. In this article, a robust controller based on extended state observer (ESO) is proposed for a dc-dc interleaved boost converter for FC application. The proportional-integral (PI) control is also designed for compariso...
