摘　　要：当空压机性能发生衰减或静态特性发生变化时,采用前馈补偿解耦闭环控制算法对车用质子交换膜燃料电池空气供应系统基于该算法进行控制的品质会变差。为此本文在前馈补偿解耦闭环控制的基础上增加了自适应查表算法,以期提高空压机转速调节能力。硬件在环仿真结果表明,改进后的自适应解耦控制算法可在线和自适应地更新空压机转速标定表,从而有效消除PI调节器积分饱和现象,使空压机响应速度更快,入堆空气流量的控制效果更好。When the performance of air compressor degrades or its static characteristics change,the control quality of the air supply system in proton exchange membrane fuel cell by using feedforward compensation decoupling closed-loop control algorithm will deteriorate.In view of this,an adaptive table-lookup algorithm is added onto the feedforward compensation decoupling closed-loop control algorithm,to enhance the speed adjustment capability of air compressor.The results of hardware-in-the-loop simulation show that the improved adaptive decoupling control algorithm can online and adaptively update the air compressor speed calibration table,thus effectively eliminating the phenomenon of integral saturation in PI regulator,speeding up the response of air compressor and improving the control effect of inlet air flow.
