Integrating identification and qualitative analysis for the dynamic model of a lagoon. (English) Zbl 1058.92044

Summary: This paper deals with the identification and the qualitative analysis of a dynamic model of a shallow lagoon. The model describes the relations between biotic (phytoplankton, zooplankton) and abiotic (oxygen, nutrients) components of a lagoon. The first step of the paper is to derive estimates for the model parameters through an identification procedure using real data. The second step is to perform a qualitative analysis of the model dynamics, via the introduction of a parameterized reduced order model. The main contribution of the paper is to make an effort in the direction of synergyzing the identification stage with the qualitative analysis of the model dynamics, in order to gain a better understanding of the system behavior and obtain more reliable estimates for the model parameters and exogenous inputs.
