摘要
提出了一种基于反馈线性化的自适应滑模控制器(FLC-ASMC)来解决车用质子交换膜燃料电池(PEMFC)系统中阴阳极气体流量与压力的协同控制问题。考虑到PEMFC系统的非线性和强耦合特点,采用反馈线性化方法解耦流量与压力的关系,从而控制阴阳极压差在合理范围内。研究结果表明,传统PID控制精度约为85%,SMC控制精度为90%~92%,而FLC-ASMC的控制精度达到95%以上,表现出最佳性能。试验验证了该控制器能够有效控制压差,提升系统的鲁棒性和使用寿命。
A feedback linearization-based adaptive sliding mode controller(FLC-ASMC)was proposed to address the coordinated control of anode and cathode gas flow rates and pressures in a proton exchange membrane fuel cell(PEMFC)system.Considering the nonlinear and strongly-coupled characteristics of PEMFC system,the feedback linearization method was used to decouple the relationship between flow rates and pressures,and the anode-cathode pressure difference was hence able to be controlled within a reasonable range.The simulation results show that the traditional PID controller achieves about 85%control accuracy,the sliding mode controller(SMC)achieves 90%-92%control accuracy,while the FLC-ASMC achieves over 95%control accuracy,showing the best performance.The experimental verification confirms that the proposed controller can effectively control the pressure difference,and hence improve the system robustness and service lifespan.
