Decoupling control and HiL verification of fuel cell air supply subsystem
针对质子交换膜燃料电池(proton exchange membrane fuel cell,PEMFC)系统的空气进气子系统,研究其阴极进气流量和阴极压力的非线性解耦及跟踪控制.分析空气进气子系统中,控制变量(空压机角速度、背压阀开度)与输出变量(阴极进气流量、电堆阴极压力)的非线性和强耦合动态特性,建立面向控制的四阶非线性动态模型.基于微分几何输入输出解耦理论,对输入变量和输出变量进行解耦,获得对应的线性化标称模型.利用极点配置方法,分别设计进气流量与阴极压力的PID跟踪控制器.基于STM32 微控制器,开发具有自主知识产权的燃料电池控制器(fuel-cell control unit,FCU),并搭建相应的硬件在环(hardware in loop,HiL)验证系统,对所开发的FCU控制器和算法进行性能验证.
This paper investigates the nonlinear decoupling and tracking control of the stack inlet airflow rate and cathode pressure in the air supply subsystem of Proton Exchange Membrane Fuel Cell(PEMFC)system.First,the nonlinear and strongly coupled dynamic characteristics between the control variables(compressor speed and back pressure valve opening)and the output variables(stack inlet airflow rate and cathode pressure)in the PEMFC air supply subsystem are analyzed.A control-oriented fourth-order nonlinear dynamic model is built.Then,the input-output decoupling theory of differential geometry is applied to decouple the input and output variables,obtaining the corresponding linearized nominal model.Next,the pole placement method is employed to design PID tracking controllers for the inlet airflow rate and cathode pressure.Finally,a Fuel-cell Control Unit(FCU)with independent intellectual property rights is developed based on the STM32 micro-controller.A corresponding Hardware-in-the-Loop(HiL)verification system is built to evaluate the performance of the developed FCU controller and algorithms.
