- Summary:
- This paper addresses a series of issues in the thermal management system of proton exchange membrane fuel cells (PEMFC) during power fluctuations, such as slow system response, insufficient stability, significant temperature fluctuations, and the complexity of coupled control between coolant flow and air flow. A solution is proposed by designing separate Linear Active Disturbance Rejection Controllers (LADRC) for the coolant flow and air flow control loops. A one-dimensional model of the PEMFC thermal management system was established on the LMS AMESIM simulation platform, combined with a hydrogen fuel cell vehicle model and a driver model, fully considering various influencing factors such as vehicle power fluctuations and driver demands. Subsequently, the LADRC control algorithm was developed on the Matlab-Simulink platform, and a co-simulation analysis was performed to compare the control effects of PID control and LADRC under both custom operating conditions and the New European Driving Cycle (NEDC) conditions.The simulation results show that with the LADRC controller, the temperature of the coolant entering the stack can be stably maintained at 65°C, and the LADRC controller can quickly respond to temperature changes during drastic condition variations. Under NEDC conditions, when the power rapidly increases, the peak temperature of the coolant exiting the stack reaches 70.5°C, which is 3.55°C lower than the temperature under traditional PID control. Additionally, the fluctuation of temperature difference of the system is kept within 7°C
