Process identification: use of algorithms in Matlab to find a model by identification for a pH measurement process

Abstract:

This raises the need to model the dynamic behavior of a pH measurement system, for which it could be considered for obtaining the physical parameters mathematical formula or by identifying a mathematical model. It starts with data obtained experimentally from a simulator, they are generated according to a PRBS signal, the information input and output of the simulator will be used for model identification. The experimental model identification is performed using the three parametric models providing Matlab functions, these are: OE, ARMAX and ARX. Finally, cross-validation is performed for each of the models and comparative analysis of the results for their selection of the mathematical model that describes the dynamic behavior of the system. This paper does not reach the controller calculation process; simply remains in the collection and model validation.
