Dynamic simulation and control of fuel cell thermal management system
摘要
Abstract
The stack temperature of proton exchange membrane fuel cell(PEMFC)rose slowly during the startup stage at room temperature,resulting in inefficient performance.There was a coupled relationship between the coolant flow rate and the cooling air flow rate.To address the slow temperature ramp-up issue during room temperature startup,a well-designed thermal management system was implemented to enhance the output performance.To tackle the coupled relationship between the coolant flow rate and the cooling air flow rate control,a joint control strategy was proposed,where the coolant flow rate was regulated based on heat control,linear self-disturbance control was applied to manage the air flow rate.This approach decoupled the control of the water pump flow rate and the cooling air flow rate.Simulation results indicated that the joint control strategy elevated the stack temperature from room temperature to 80 ℃ within 100 s.The temperature difference between the coolant entering and exiting the stack stabilized at 5℃.When subjected to input disturbances,the stack temperature exhibited only a 0.5％overshoot and returned to 80 ℃ within 50 s.The overshoot was merely 8.82％of the proportional-integral-derivative controller(PID)'s response time,resulting in a 50 s improve-ment in response speed.The control strategy proved to be more effective in managing the stack temperature and the temperature difference between coolant entering and exiting stack.关键词
