Discussion on: 'A Stacked Model Structure for Off-line Parameter Variation Estimation in Multi-equilibria Nonlinear Systems'

摘要

The paper by Collins et al. presents an approach for estimating the parameter variation of a nonlinear system using data from equilibrium points. The authors establish necessary and sufficient conditions to render the parameter vector observable in the senor data collected about an appropriate number and combination of equilibrium points. A classical nonlinear filter is then applied to estimate the parameter variation vector as part of the augmented state vector.
