Abstract:

The mode of greenhouse environment is a important basis of instituting control tactic and optimizing control method. The RBFNN is constructed environmental control model inside greenhouse in the north of China. NN outputs were temperature and humidity inside greenhouse. NN hidden unit centers were optimized, and NN configuration was simplified by means of ES. Both algorithms were compared. Experiment result is showed: approximate and generalization ability of RBFNN based on ES is better to OLS algorithm. The model is beneficial to design control scheme and configuration of the north greenhouse.
