基于ADHDP的PEMFC温度控制

Temperature control of PEMFC based on ADHDP

以质子交换膜燃料电池(PEMFC)非线性控制系统为研究对象,采用执行依赖启发式动态规划(ADHDP)实现对PEMFC温度的控制。首先建立PEMFC的电堆温度动态模型;然后利用ADHDP算法设计PEMFC发电系统温度控制器;最后用Matlab/Simulink仿真平台对启发式动态规划(HDP)、比例积分微分(PID)和ADHDP设计的温度控制器进行对比。ADHDP控制器控制的电堆温度的超调量仅为0.59%,小于HDP的0.94%和PID的4.47%,该ADHDP控制器可提高PEMFC温度控制的稳定性,能更好地改善系统的动态性能,具有更好的温度控制效果。

The proton exchange membrane fuel cell(PEMFC)nonlinear control system was taken as the research object.In order to realize the method of implementing PEMFC temperature control,the action dependent heuristic dynamic programming(ADHDP)was adopted.Firstly,the dynamic model of stack temperature of PEMFC was established.Then,the ADHDP was used to design the temperature controller of PEMFC powers generation system.Finally,the temperature controllers of heuristic dynamic programming(HDP),proportional integral derivative(PID)and ADHDP were compared by Matlab/Simulink simulation platform.The overshoot of stack temperature controlled by ADHDP controller was only 0.59%,less than 0.94%of HDP and 4.47%of PID.The stability of PEMFC temperature controller was enhanced by the ADHDP controller.The dynamic performance of the system was improved better and the temperature was controlled effectively.
