基于模糊自抗扰的PEMFC输出电压控制研究
Research on PEMFC output voltage control based on fuzzy active disturbance rejection
摘要
Abstract
In allusion to the problems of unstable output voltage and low power generation efficiency of proton exchange membrane fuel cell(PEMFC)after self startup,a control strategy based on fuzzy self disturbance rejection controller is proposed to improve the output voltage stability of PEMFC.On the basis of establishing the PEMFC electrochemical dynamic model,an optimized self disturbance rejection controller is used to estimate and compensate for the total disturbance received by the system in real time,track the output voltage,and add a fuzzy controller to achieve self tuning of the dual parameters within a limited range.The effectiveness of the control technology was verified by the simulation experiments,and the comparison analysis is conducted with proportional integral derivative(PID)and conventional self disturbance rejection control methods.The results show that the proposed control strategy can effectively reduce the voltage oscillation amplitude of PEMFC,make the PEMFC voltage reach a stable state,and the closed-loop system has the smallest overshoot and the shortest adjustment time under the same disturbance.The system has better robustness and anti-interference ability.关键词
