摘　　要：本文以固体氧化物燃料电池发电系统(SOFC)为对象,提出基于模糊-PID的发电逆变控制方法,对其发电输出逆变系统以及输出电压控制进行详细地分析.在整个系统中采用了隔离型改进升压变换器和反激式绕组用以提高直流系统电压的稳定性.本文提出改进型模糊PID控制方法以改善系统电压不稳定的问题,其仿真结果表明,该控制方法对于整个系统具有较好的适用性.In this paper,solid oxide fuel cell(SOFC) is taken as the power generation,and its mathematical model,inverter system and output voltage control strategy are analyzed. The improved isolated boost converter is applied to the solid oxide fuel cell inverter system,and the fly-back winding is added to the DC-DC converter to improve the stability of the DC bus voltage. For solid oxide fuel cell voltage instability problems,put forward the improvement of solid oxide fuel cell output voltage control strategy,simulation analysis shows that the fuzzy-PID control strategy is more suitable for solid oxide fuel cell power generation system.
