【摘要】 在所有类型的燃料电池中,质子交换膜燃料电池因具有质量轻、效率高、电流密度大、工作温度低、启动速度快以及使用无毒性的固态电解质膜等优点近年来发展最快。针对这种燃料电池的输出功率,首先提出了一阶滞后数学模型,而后给出一种预测控制算法,并讨论了控制器参数的设计,该算法改善了燃料电池的输出特性。仿真结果验证了所提算法的有效性。更多还原

【Abstract】 Because of lightweight, high efficiency and power density, low operating temperature, rapid start up and using innocuous solid proton conduction electrolyte, the proton exchange membrane fuel cell (PEMFC) are at present in the forefront of all types of fuel cell. A first-order with dead-delay was described as a fuel cell model. To improve output performance of the fuel cell,a new predictive control algorithm was presented, and the controller parameters were discussed. The simulation validated the effectiveness of the algorithm proposed.更多还原
