System for optimizing working point of drying control system after new energy battery coating in real time

The invention relates to a real-time optimization system for a working point of a drying control system after coating of a new energy battery, which is characterized in that a multi-objective optimization function is constructed based on energy consumption and an NMP concentration index, and a control objective of the NMP concentration, the frequency of an internal circulating fan and the lowest frequency of an external circulating fan are determined by solving the optimization problem; wherein the constructed optimization problem objective function is realized by solving a linear optimization method with constraints. When the RTO optimization control module is called each time, the optimal NMP concentration control target, the optimal internal circulating fan target and the optimal external circulating fan frequency lower limit protection value in the next calling period are obtained by solving the optimization problem, and the total circulating air volume of the system is reduced as much as possible on the
