Integrated fuel cell thermal management system based on hybrid theory and control method thereof

The invention discloses an integrated fuel cell thermal management system based on a hybrid theory and a control method thereof, and belongs to the technical field of fuel cell automobile thermal management. The system comprises a plurality of working modes including fuel cell coolant large and small circulation, electric drive coolant circulation and electric drive waste heat heating fuel cell coolant circulation, various thermal management requirements under the all-weather condition are covered, and energy consumption is reduced through reasonable waste heat utilization. In addition, the connection relation of all the components in the integrated fuel cell thermal management system is easy to implement, and the control logic is simple and clear; the hybrid logic dynamic model in the hybrid theory is adopted to model the mode switching process in the integrated fuel cell thermal management system, and hybrid model predictive control is developed based on the hybrid logic dynamic model mode switching model t
