【摘要】 车用燃料电池在实际工况中容易产生供气波动、内部温度分布不均等问题导致阳极内部压力不稳定,严重影响了其市场化推广。通过控制方式的设计可以优化上述问题,针对质子交换膜燃料电池(PEMFC)阳极压力的仿真、跟随和控制等问题,论述了基于自抗扰原理的质子交换膜燃料电池死端模式阳极的建模过程,并在Simulink环境下通过仿真证明了基于自抗扰原理控制方式的有效性。仿真结果验证了该仿真系统的实用性和有效性,该仿真系统能够使质子交换膜燃料电池阳极压力有效跟随阴极压力,能够对温度、压力变化等扰动具有抵抗效果,跟随速度快,准确度高,超调极少。
【Abstract】 Automotive fuel cells are prone to pressure fluctuations and uneven internal temperature distribution under actual working conditions, resulting in unstable internal pressure of the anode, which seriously affects its marketization. The above problems can be optimized through the design of the control method,this paper aims at the problems of simulation, following and control of anode pressure of proton exchange membrane fuel cell(PEMFC), the modeling process of anode of PEMFC based on active disturbance rejection principle is discussed, and a simulation system using anode dead end mode is designed. The effectiveness of the control method based on active disturbance rejection principle is proved by simulation. The simulation results verify the practicality and effectiveness of the simulation system. The simulation system can make the anode pressure of proton exchange membrane fuel cell effectively follow the cathode pressure, and can resist the temperature, pressure changes and other disturbances. The following speed is fast, the accuracy is high, and the overshoot is very small.
