Abstract

This study introduces a dynamic mathematical model for the thermal management system of the stack, incorporating a circulating water pump and radiator. The control strategy integrates feedforward and feedback mechanisms, focusing on regulating cooling water flow based on current and utilizing a fan to control stack temperature. An innovative approach is applied to enhance the first-order deviation active disturbance rejection control algorithm. This involves extracting deterministic model information to elevate the temperature control precision within the thermal management system. Simulation results demonstrate that the effectiveness of the proposed improved ADRC control algorithm in addressing challenges related to strong coupling and multiple disturbances inherent in PEMFC thermal management systems. Comparative analysis against a conventional proportional-integral control algorithm reveals significant improvements in the closed-loop control system. Specifically, the enhanced ADRC algorithm achieves a 43.7% reduction in overshoot and a 20.2% decrease in adjustment time. These results underscore the system's robustness and anti-interference capabilities, affirming its ability to attain the desired control outcomes.
