A decoupling control system is designed by a simple tuning-free method for the multi-input multi-output model of a proton exchange membrane fuel cell. The decoupler minimizes the interactions among the loops and is designed by estimating the relative normalized gain array and dynamic relative gain array for the closed-loop model. The proportional integral controller settings are estimated using the partial model matching method. The performances of the proposed method are studied based on closed-loop performances of control variables and time integral errors that are compared with the synthesis method. The proposed controller performs better in terms of integral of time-weighted absolute error.

一种设计质子交换膜燃料电池去耦器的简单方法 

针对质子交换膜燃料电池的多输入多输出模型，采用简单的免调谐方法设计了解耦控制系统。解耦器最大限度地减少环路之间的相互作用，并通过估计闭环模型的相对归一化增益阵列和动态相对增益阵列来设计。使用部分模型匹配方法估计比例积分控制器设置。基于控制变量的闭环性能和时间积分误差与综合方法进行了比较，研究了该方法的性能。所提出的控制器在时间加权绝对误差的积分方面表现更好。
