摘　　要：本文对水冷质子交换膜燃料电池进行了分阶段控温建模。在冷液-热液混合控温阶段,通过反馈线性化方法解决了系统的非线性特性。仿真结果表明,采用反馈线性化方法后,再结合PID控制就能够实现良好的控温效果。在散热风扇控温阶段,采用基于Lyapunov稳定性理论的模型参考自适应控制设计方法,设计了模型跟随控制器及其对应的自适应控制律。仿真结果表明,在燃料电池系统载荷变化、水泵转速变化和工作环境温度变化等情况下,仍可实现控温目标的一致跟随。This article presents a staged temperature control modeling of water-cooled proton exchange membrane fuel cells(PEMFC).In the temperature control stage of cold coolant and hot coolant mixture,the nonlinear characteristics of the system were solved through feedback linearization control method.The simulation results show that using feedback linearization method combined with PID control can achieve good temperature control effect.In the temperature control stage of the cooling fan,a model reference adaptive control design method based on Lyapunov stability theory was adopted to design a model following controller and its corresponding adaptive control law.The simulation results indicate that consistent tracking of control objectives can still be achieved under conditions such as changes in fuel cell system load,pump speed,and working environment temperature.
