A New Strategy of Validities’ Computation for Multimodel Approach: Experimental Validation

Abstract

Abstract-The evaluation of validities is a fundamental step in the design of the multimodel approach. Indeed, it is thanks to validities that we estimate the contribution of each base-model in the reproduction of the behavior of the global process in a given operating area. These coefficients are calculated most commonly by the approach of the residues formulated by the distance between the real output and the sub-models' outputs. In this paper, a strategy allowing to improve the performances of the residues' approach in terms of precision and robustness is proposed. This strategy is based on a quasi-hierarchical structuring. A simulation example and a validation on a semibatch reactor showed the interest and the effectiveness of the proposed strategy.

Multimodel Representation of Complex Nonlinear Systems: A Multifaceted Approach for Real-Time Application

“…A neural network is used to create the validity demonstrate a very significant results in the synthesis of the multimodel is explained in [8]. Other specific method are also represented in [9][10][11][12]. A great importance was considered to the work presented in Elfelly [13].…”
