Use of subspace identification techniques for solar fields mathematical modeling

Concentrated solar fields (CSP) are used for the generation of electric energy through the conversion of thermal energy into electricity. Due to the complexity of the process of dynamic behavior, identification techniques are an alternative to the use of mathematical models based on phenomenological equations. The use of subspace identification technique for the deterministic-stochastic case in this paper has proved to be interesting from the point of view of the prediction of the behavior of the output temperature of the solar field. Moreover, the linear time-invariant state-space model can be used in designing model-based controllers.
