Nonlinear Anti-windup Control Based on a Gain-Scheduling Algorithm

Gain-scheduled, model-based anti-windup for LPV systems

The aim of this paper is to show that a recently proposed technique for anti-windup control of exponentially unstable plants can be easily extended to solve the corresponding robust anti-windup problem for linear parameter varying systems, for which the time varying parameters are measured online. The proposed technique is minimally conservative with respect to the size of the resulting operati...

Fuzzy Gain-Scheduling Control of Nonlinear Processes

Fuzzy gain-scheduling is a special form of model-based fuzzy control that uses linguistic rules and fuzzy reasoning to determine the controller parameter transition policy for a dynamic plant subject to large changes in its operating state. Issues of stability and overall dynamic behavior are resolved using conventional modern control techniques. The design of a fuzzy gain-scheduling controller...

Nonlinear Dynamic Inversion Based Anti-windup - An Aerospace Application ?

A recently suggested general anti-windup (AW) compensation scheme is applied to the nonlinear simulation model of the 1 16 scaled BAe Hawk aircraft model used for wind tunnel experiments. The Hawk is modelled as a nonlinear affine system subject to input constraints and has a primary control system consisting of an inner-loop nonlinear dynamic inversion controller and an outer-loop linear PID c...

Nonlinear L2 Gain and Regional Analysis for Linear Systems with Anti-Windup Compensation

In this paper, we address regional stability and performance analysis on linear control systems with linear anti-windup augmentation. We use LMIs to compute 1) an upper bound for the nonlinear L2 gain, 2) an estimate of the reachable set under norm bounded exogenous input and 3) an estimate of the domain of attraction with zero input. The problems are studied in a general setting where the only...
