Model based and empirical approaches to robust control structure selection based on the H2-norm
2012 (English)Conference paper, Presentation (Refereed)
This paper presents a method for the robust control structure selection based on the assessment of the H2-norm. For both uncertain parametric models and non parametric estimated frequency response functions (FRF) with confidence regions, the magnitude of the Bode diagram is analyzed and regions for the H2-norm are derived. The H2-norm has been successfully used to identify the significant input-output interconnections in multivariable system for the nominal case. The derived regions for the H2-norm of the interconnections are used to extent the H2-norm based method to the uncertain case, and enables robust control structure selection. The method is applied to theoretical examples and a quadruple tank setup to shows its feasibility.
