This paper presents a Principal Component Analysis (PCA) study for neuronal modelling of a complex system. The PCA transforms a set of correlated variables into a smaller set of uncorrelated variables without lose the original information. Thanks to this first stage it is possible to design a simplified structure of the model. The right choice of the architecture is crucial for the application of neural nets in process identification. The proposed study allows to validate the association of the PCA with neuronal model for a real multivariable process modelling: an experimental greenhouse. The object is to estimate the internal climate (temperature and hygrometry) by reducing the number of the input variables. Thus, we compare two different structures of neural networks. Several tests and results are presented and discussed.
