Breton. Gain scheduling. In designing feedback controllers for dynamical systems a variety of modern, multivariable controllers are used. In general, these controllers are often designed at various operating points using linearized models of the system dynamics and are scheduled as a function of a parameter or parameters for operation at intermediate conditions.

PY - /9/ Y1 - /9/ N2 - LPVTools is a MATLAB toolbox that is being developed to perform gain-scheduled Linear Parameter-Varying (LPV) control. As is already emphasized in previous chapters of this book, Linear Parameter Varying (LPV) control techniques have known a large success over the past 15 years.

LMI relaxations for robust gain-scheduled control of uncertain linear parameter varying systems Abstract: This study deals with the problem of robust gain-scheduled dynamic output feedback control for uncertain discrete-time linear parameter varying systems.

The design of state feedback gain-scheduled controllers for linear parameter-varying systems with saturating actuators is addressed in the paper.

The parameters can vary arbitrarily fast inside a polytope with known vertices. Sufficient conditions for the existence of gain-scheduled controllers assuring asymptotic stability for initial conditions inside a region of the state space are provided.

The main goal of this work is to study the stability properties of an aircraft with nonlinear behavior, controlled using a gain scheduled approach. An output feedback is proposed which is able to guarantee asymptotical stability of the task-coordinates origin and safety of the operation in the entire flight envelope.

The results are derived using theory of hybrid and singular perturbed systems. The control design uses a 6-DOF nonlinear dynamic model that is manipulated into a pseudo-linear form where system matrices are given explicitly as a function of the current state.

A standard Riccati equation is then solved numerically at each step of a 50 Hz control loop to design the nonlinear state feedback control law on-line. The approach combines LPV theory based on Linear Matrix Inequalities (LMIs) and μ-synthesis to form a new robust approach for large envelope control design.

The new approach is used to design an automatically gain-scheduled pitch-rate controller for the F Variable Stability In-Flight Simulator Test Aircraft (VISTA). Linear parameter varying (LPV) techniques provide a framework for modeling, analysis, and design of the control laws across the flight envelope.
