To effectively control the thermal management system of a dualstack fuel cell system, this paper establishes a fuel cell stack model based on test data, and couples it with key component models such as pumps and heat exchangers to form a complete thermal management system model. To stabilize the stack temperature under disturbances, a control strategy combining proportionalintegral (PI) with linear active disturbance rejection control (LADRC) was proposed and verified by simulation. Finally, an improved control strategy based on feedforward decoupling and cascade LADRC was proposed. The control effects before and after the improvement were compared through simulation. The results show that the improved control strategy can effectively reduce overshoot, and the integral time absolute error (ITAE), reflecting temperature control accuracy, can be reduced by up to 66.39%.
