摘　　要：为简化质子交换膜燃料电池系统中空气压力和空气流量解耦控制算法,在充分分析现有燃料电池系统中普遍使用的离心式空压机特性的基础上,提出一套基于PID和模糊控制的无解耦空气压力、空气流量闭环算法。将该控制算法在空气供应子系统台架和质子交换膜燃料电池系统上进行了测试,结果表明:空气压力和空气流量在燃料电池系统稳态运行时误差分别在1 kPa及1 g/s以内,该算法控制效果良好,精度满足实际需求,且可以很好地规避空压机喘振问题。In order to simplify the air pressure and air mass flow rate decoupling control algorithm of Proton Exchange Membrane Fuel Cell(PEMFC),based on the deep analysis of centrifugal air compressors,which are widely used in current fuel cell system,this paper proposes a non-decoupling air pressure and mass flow rate double closed-loop algorithms based on PID and fuzzy control.The control algorithm is verified on an air supply subsystem test bench and a real PEMFC system.The test results show that error of air pressure and air mass flow can be controlled at 1 kPa and 1 g/s respectively at steady-state operation of fuel cell system,and the algorithm has a good control performance,the accuracy meets the actual demand,and it can well avoid the air compressor surging.
