Automated Generation of LFT-Based Parametric Uncertainty Descriptions from Generic Aircraft Models
A computer assisted modelling methodology is developed for the generation of linearized models with parametric uncertainties described by Linear Fractional Transformations (LFTs). The starting point of the uncertainty modelling is a class of generic nonlinear aircraft models with explicit parametric dependence used for simulation purposes. The proposed methodology integrates specialized softwar...
متن کاملFrom Generic Aircraft Models towards LFTs Based
A computer assisted modelling methodology for the generation of linear models with LFTs based parametric uncertainty descriptions is proposed. The starting point for the LFT modelling is a class of generic nonlinear aircraft models used for simulation purposes. The proposed methodology integrates many specialized software tools for object-oriented modeling, for simulation and numerical computat...
متن کاملGeneralized Lft-based Representation of Parametric Uncertain Models
In this paper we introduce a general descriptor-type LFT representation of rational parametric matrices. This generalized representation allows to represent arbitrary rationally dependent multivariate functions in LFT-form. As applications, we develop explicit LFT realizations of the transfer-function matrix of a linear descriptor system whose state space matrices depend rationally on a set of ...

REPEATED PARAMETRIC UNCERTAINTIES K. B. Lim , D. P. Giesyy NASA Langley Research Center, MS 161, Hampton, Virginia, 23681-0001 Abstract A new methodology in which linear fractional transformation uncertainty bounds are directly constructed for use in robust control design and analysis is proposed. Existence conditions for model validating solutions with or without repeated scalar uncertainty ar...
متن کاملRobustness Analysis Applied to Autopilot DesignPart
In this contribution the automated generation of LFT-based parametric uncertainty descriptions from a generic nonlinear aircraft-dynamics model, as used for the GARTEUR RCAM Design Challenge on Robust Flight Control, is described. For this purpose an object-oriented, equation-based modeling approach using the modeling environment Dy-mola was applied. Using this technique allows the modeling of ...
