Automatic Intermittent Humidification Control Systems based on Grey Box Models

As living standards are improving, people have higher requirements for comfort and health in their living environment. Indoor temperature and humidity are two important factors that affect human comfort. Previous research has mainly focused on indoor temperature environment, while research on humidity environment is relatively simple, usually only considering energy consumption and humidity stability issues. Therefore, traditional humidity control methods can no longer meet the needs of intermittent use of houses. This article establishes gray box models of humidification room systems and estimates the time required for advance humidification based on the models. Subsequently, a fully automatic intermittent humidification control system is designed using MATLAB and STM32, which achieved functions such as user interaction interface, data automatic acquisition, model automatic identification, and algorithm automatic execution. Finally, the effectiveness and universality of the fully automatic intermittent humidification control system are verified through experiments.
