A method to construct reduced‐order parameter‐varying models
Jennifer Annoni,Peter Seiler +1 more
TL;DR: In this paper, a reduced-order linear system is constructed at each equilibrium point using state, input, and output data, and a parameter varying linearization is used to connect these linear models across the various operating points.

Interpolated Modeling of LPV Systems
TL;DR: This paper presents a new state-space model interpolation of local estimates technique to compute linear parameter-varying (LPV) models for parameter-dependent systems using a set of linear time-invariant models obtained for fixed operating conditions.

LPV Modeling of a Flexible Wing Aircraft Using Modal Alignment and Adaptive Gridding Methods.
TL;DR: The notion of σ-shifted and [Formula: see text]-norm are introduced and used as a metric to measure the model mismatch and a new modal alignment algorithm is developed which utilizes the defined metric for aligning all the local models over the entire gridded parameter space.

Modal Matching for LPV Model Reduction of Aeroservoelastic Vehicles
TL;DR: A model order reduction method is proposed for models of aeroservoelastic vehicles in the linear parameter-varying (LPV) systems framework, based on state space interpolation of modal forms, to transform the resulting collection of systems into a consistent modal representation suitable for interpolation.

An iterative SVD-tangential interpolation method for medium-scale MIMO systems approximation with application on flexible aircraft
TL;DR: This paper provides a simple but numerically robust and effective procedure, namely, Iterative SVD-Tangential Interpolation Algorithm (ISTIA), to approximate any medium-scale MIMO LTI system and assesses the efficiency of the proposed methodology on a medium- scale industrial aeroelastical aircraft model, on which different control design methodologies are evaluated.

Survey of Gain-Scheduling Analysis & Design
TL;DR: The scope of this paper includes the main theoretical results and design procedures relating to continuous gain-scheduling (in the sense of decomposition of non-linear design into linear sub-problems) control with the aim of providing both a critical overview and a useful entry point into the relevant literature.

$\mathcal{H}_2$ Model Reduction for Large-Scale Linear Dynamical Systems
TL;DR: A new unifying framework for the optimal $\mathcal{H}_2$ approximation problem is developed using best approximation properties in the underlying Hilbert space and leads to a new set of local optimality conditions taking the form of a structured orthogonality condition.

Analytical framework for gain scheduling
TL;DR: A framework for the design of `idealized' gain-scheduled controllers for nonlinear systems is discussed, and implications are drawn for `practical' design situations.
