摘要
回顾了近年来质子交换膜(PEM)电化学系统瞬态温湿度场测量和性能评价的相关研究,以及循环启停及长期运行下的系统控制策略(包括PID、神经网络及模糊控制等)。由于PEM系统运行涉及传热传质、电化学反应等复杂过程,理论建模比较复杂;数据驱动模型能够有效结合理论模型及实验数据、且求解简单。近年来新发展的智能PID控制策略在多输入多输出系统中具有较好的抗扰性和响应速度。通过与数据驱动模型结合,被认为是准确预测PEM系统的性能和寿命、提升PEM电化学系统动态性能的有效方案。
This paper introduced the relevant research on the transient temperature and humidity field measurement and performance evaluation of proton exchange membrane(PEM)electrochemical systems in recent years,and summarized the system control strategies(including PID,neuron network and fuzzy control,etc.).Intelligent PID control technologies such as fuzzy and neural networks have developed rapidly,and have better immunity and response speed in multiple-input and multiple-output systems.Since the proton exchange membrane system involves complex processes such as heat and mass transfer,electrochemical reactions,etc.,the theoretical modeling is relatively complex.Data-driven models can effectively combine theoretical models and experimental data and are simple to solve.It can provide operation data for PID real-time control and is an effective solution to improve the dynamic characteristics of PEM electrochemical system.
