This paper is concerned with synthesis of gain-scheduled controllers by representing LPV systems in the descriptor form. Based on a recent algebraic criterion characterizing dissipativity of descriptor systems, an improved synthesis method is proposed with removing limitations of descriptor representation in existing results. Specifications of exponential decay are also considered. A numerical ...

This paper presents a systematic framework of gainscheduled controller synthesis for a class of LPV systems. The main contribution of this paper comes from two aspects. First, a novel class of controller structure is introduced specifically for the class of LPV systems considered. The advantage offered by this class of controller structure is that the controller synthesis can be more easily for...

In this paper we present the design process and results for a re-entry baseline controller used as a benchmarking reference within a European Space Agency (ESA) project on advanced gain-scheduling techniques. The controller is based on output gain-scheduling of a set of LTI H∞ controllers obtained using a decoupled motion approach. The rationale behind the selection of the design points, and th...

LPVTools is a MATLAB toolbox that is being developed to perform gain-scheduled Linear Parameter-Varying (LPV) control of aeroservoelastic systems. This paper outlines the LPV modeling, analysis and controller synthesis features of this toolbox. The features of the toolbox are illustrated by an application example, where a grid-based LPV model is developed for the X-56A aircraft using LPVTools. ...

The main objective of this research is to improve the feasibility of Energy Momentum Wheels for satellite systems through the development of robust LTI and gain-scheduled controllers for high-speed flywheel rotors supported on active magnetic bearings. A hybrid combination between H∞ loop-shaping and μ-synthesis is used in this paper to design controllers. In order to reduce the computational c...

Abstract: Despite continuous research effort, patients with type 1 diabetes mellitus (T1D) experience difficulties in daily adjustments of their blood glucose concentrations. New technological developments in the form of implanted intravenous infusion pumps and continuous blood glucose sensors might alleviate obstacles for the automatic adjustment of blood glucose concentration. These obstacles...

This paper proposes a method to obtain a discrete-time LPV (Linear Parameter Varying) controller for a non-linear system represented with the LFT (Linear Fractional Transformation) framework. This synthesis can be integrated into a loop-shaping/LPV approach to obtain a discrete gain-scheduled control law. A detailed application of this method is here performed with a classical example of non-li...

The mitigation of peak-valley difference and transient power fluctuation are both great significance to the economy stability grid. This paper proposes a novel vehicle-to-grid behavior management method that can provide peak-shaving fast balancing service grid simultaneously. Firstly, multi-time scale framework is designed enable large-scale optimization real-time control at same time in schedu...
