摘要
给出了PEMFC(Proton Exchange Membrane Fuel Cell)空气供给系统的数学模型,基于simulink进行了模型的仿真,仿真结果和实验证明了PEMFC空气供给系统模型是正确有效的,能够准确地反映PEMFC空气供给系统的动态变化趋势。设计了PEMFC空气供给自适应模糊PID控制算法,根据建立的控制对象模型,进行控制系统的仿真,仿真结果与实验结果证明设计的自适应模糊PID控制方法使系统响应时间短,稳态误差小,达到较理想的控制性能目标。
The article introduces the mathematical model of air supply system in Proton Exchange Membrane Fuel Cell(PEMFC),the simulation of the model based on simulink is also introduced.The simulation and experiment results prove that the model of air supporting system in PEMFC is correct and effective,and reflect exactly the dynamic change trend of air supporting system in PEMFC.The design of self-adaptive fuzzy PID control arithmetic in PEMFC is discussed based on the model of control object,The simulation of the control system is also introduced.The results based on the simulation and the experiment prove that the design of self-adaptive fuzzy PID control method make the system has rapid response and less steady-state errors,can obtain ideal control performance index.
