燃料电池空气系统LADRC-SMC复合控制策略研究
Control strategy of fuel cell air system based on LADRC-SMC
摘要
Abstract
To address the slow tracking speed and significant oscillation in the optimization control of the oxygen excess ratio(OER)in the air system of proton exchange membrane fuel cells(PEMFC),this paper proposes a control algorithm that integrates a fuzzy extended state observer(FESO)with a second-order linear active disturbance rejection control(LADRC)and sliding mode control(SMC).First,considering the dynamic characteristics of the PEMFC system,a control-oriented fourth-order state space model is built.Then,a linear active disturbance rejection control and sliding mode coupling controller is designed.On this basis,a fuzzy control-improved extended state observer is proposed to observe disturbances,enabling the oxygen excess ratio(OER)to approach the optimal value steadily and rapidly.Results show,under a quantifiable weighted evaluation system,the control strategy improves the score by 19.2％ and 10.9％ respectively compared to those of the traditional PID and fuzzy PID control methods,demonstrating its superior ability to improve control accuracy and disturbance rejection capability under current disturbances.关键词
