Bi-objective system identification using Polynomial NARX models minimizes dynamic and static errors via Pareto-optimal solutions.

Dynamic Systems Identification (Polynomial Models)

Description:

The Bi-Objective Dynamic Systems Identification (BODSI) class offers a robust framework for identifying dynamic systems modeled by Polynomial NARX structures. It adopts a bi-objective parameter estimation technique where the first equation minimizes the dynamic error, and the second equation ensures precise static curve fitting. The BODSI_TOOKIT class includes functionalities for generating candidate terms, identifying clusters, constructing dynamic and static matrices, and parameter mapping, in addition to advanced decision-making tools based on model correlation. This ensures unbiased parameter estimation and allows users to visualize static models, validate dynamic performance, and select optimal solutions for their specific needs.
