Modeling and Validation of Nonlinear Feedback Systems

Model validation provides a useful means of assessing the ability of a model to account for a specific experimental observation, and has application to modeling, identification and fault detection. Prior theoretical and application work in the area of model validation for robust control models focused on linear fractional models. In this paper we discuss the extension of these methods to certain classes of nonlinear models. The Moore-Greitzer model of rotating stall is used as a simple example to illustrate the underlying ideas.ISSN:0170-8643ISSN:1610-741
