摘　　要：针对传统温度控制方法在水冷型质子交换膜燃料电池(PEMFC)冷却系统中应用时出现温度波动较大、调控时间长、能耗高等问题,以某款氢燃料电池冷却系统为研究对象,利用一维软件搭建氢燃料电池冷却系统计算模型,并对标台架试验,验证了计算模型的可靠性。在此基础上,设计开发模型预测控制器,经计算分析可得,相比于原有PID控制器,采用模型预测控制(MPC)策略的PEMFC温控能力更强,温度波动明显得到改善,同时降低了氢燃料电池冷却系统的能量消耗。For the problems of large temperature fluctuation,long control time and high energy consumption in the water-cooled Proton Exchange Membrane Fuel Cell(PEMFC)cooling system of the traditional temperature control method,a hydrogen fuel cell cooling system is used as the research object,a calculation model of the hydrogen fuel cell cooling system is built using one-dimensional software,and the reliability of the calculation model is verified through bench tests.Based on these,the MPC controller is designed and developed.Calculation and analysis show that,PEMFC using MPC control strategy has better temperature control ability,obviously improves the temperature fluctuation compared with the original PID control strategy.At the same time,it also reduces the energy consumption of the hydrogen fuel cell cooling system.
