Problems solved by technology

Although the above modeling methods can solve the modeling problems of hydrogen energy reactors, there are still the following deficiencies: (1) The establishment of the mechanism model is relatively complicated, with a large amount of calculation, time-consuming, and poor real-time performance, which is not suitable for actual industrial field applications; (2) The establishment of the empirical model is often influenced by humans, and the model optimization is not sufficient; (3) Since the performance of hydrogen energy reactors has time-varying characteristics, and the above two types of models with fixed structures and parameters do not have online optimization capabilities, they cannot Fully meet the modeling requirements of hydrogen energy reactors
