摘要
为对双堆燃料电池热管理系统进行有效控制,基于试验数据建立了电堆模型,并耦合水泵、换热器等关键零部件模型形成完整的热管理系统模型.为保证阶跃工况下电堆温度的稳定,设计了基于比例积分与线性自抗扰算法的联合控制策略,并进行仿真验证.提出了基于前馈解耦及串级LADRC的改进控制策略,通过仿真对比改进前后的控制效果.结果表明,改进后的控制策略能有效减小超调量,反映温控精度的时间乘绝对误差积分量最高可降低66.39%.
Abstract
To effectively control the thermal management system of a dual-stack fuel cell system,this paper establishes a fuel cell stack model based on test data,and couples it with key component models such as pumps and heat exchangers to form a complete thermal management system model.To stabilize the stack temperature under disturbances,a control strategy combining proportional-integral(PI)with linear active disturbance rejection control(LADRC)was proposed and verified by simulation.Finally,an improved control strategy based on feedforward decoupling and cascade LADRC was proposed.The control effects before and after the improvement were compared through simulation.The results show that the improved control strategy can effectively reduce overshoot,and the integral time absolute error(ITAE),reflecting temperature control accuracy,can be reduced by up to 66.39%.
