燃料电池空气进气子系统解耦控制及HiL验证
Decoupling control and HiL verification of fuel cell air supply subsystem
摘要
Abstract
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.关键词
