摘要
质子交换膜燃料电池(PEMFC)是一个复杂的非线性系统.针对其输出电压不稳定且电压调节范围较小,作者设计了基于模糊PID控制的DC-DC变换器进行稳压.根据DC-DC变换器输出电压偏差E和偏差变化率Ec,利用设计的模糊规则,调整PID控制器的参数,改善控制效果.在MATLAB软件中建立了基于模糊PID控制的燃料电池DC-DC变换器稳压模型,进行仿真研究.建立燃料电池稳压实验系统,进行实验验证.仿真和实验结果表明,设计的基于模糊PID控制的DC-DC变换器,具有良好的稳压能力和较强的鲁棒性.
Abstract
Proton exchange membrane fuel cell(PEMFC)is a complexand nonlinear system.In response to its unstable output voltage and small voltage regulation range,a DC-DC converter based on fuzzy PID control for voltage stabilization is designed in this paper.Based on the output voltage deviation and deviation rate of the DC-DC converter,the fuzzy rules designed are used to adjust the parameters of the PID controller and improve the control effect.A voltage stabilizing model of PEMFC DC-DC converter based on fuzzy PID control is established in MATLAB software for simulation research.A fuel cell voltage stabilization experimental system is established for experimental verification.The simulation and experi-mental results show that the designed DC-DC converter based on fuzzy PID control has good voltage stabilizing ability and strong robustness.
