Modeling and simulation of indoor environment parameters based on least squares

Indoor building environment for energy saving and human health has important significance and the main criterion for evaluating its quality is environmental comfort. An experimental scheme for obtaining the mathematical model of the main parameters is designed by analyzing the parameters that affect the environmental comfort. The scheme establishes a discrete bilinear model with parameters and control variables, and uses the the least squares method to obtain the model parameters based on the experimental data. The simulation results show that the experimental scheme of this paper has strong universality and adaptability, and the model with the deviation of the real system is small, which can be used as the model basis for optimizing the control of the indoor building environment.
