摘　　要：在已有的45 k W级质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)发动机模型的基础上,将电堆冷却液旁通阀开度、大循环旁通阀开度、水泵转速、风扇开度设定为操控变量,电堆温度设定为输出量,分别设计了单点线性化全工况预测控制(Model Predictive Control,MPC)控制器和两点线性化双MPC控制器,对PEMFC发动机电堆温度进行控制和分析。在相同的仿真环境条件下,分别运行两种控制算法进行仿真运算,并对其结果进行对比分析。仿真试验结果表明,两点线性化双MPC控制的控制效果优于单点线性化全工况MPC控制。Based on the 45 kW PEMFC engine model, a single point linearization MPC controller for all conditions and a two-point linearization double MPC controller were designed to control and analyze the stack temperature. The control variables include the opening degree of the stack coolant bypass valve, the opening degree of the big cycle bypass valve, the pump speed and the opening degree of the fan and the stack temperature is output variable. Under the same simulation conditions, the simulation results of the two control algorithms were compared and analyzed. It is concluded that the control either of the two-point linearization double MPC controller is better than that of the single point linearization MPC controller for all conditions.
