Robust H2 switching gain-scheduled controller design for switched uncertain LPV systems

In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...

Robust servomechanism with preview action for polytopic uncertain systems

This paper considers the robust servomechanism design for a polytopic uncertain system subject to a previewable reference signal. Based on the robust mixed LQ/H= criterion, we develop a design method of a state feedback controller with integral and preview actions achieving the robust tracking performance in terms of linear matrix inequalities. A numerical example is also included to show the a...

Reduced complexity existence conditions for robust L2-gain feedforward controllers for uncertain systems using dynamic IQCs

For uncertain systems described in the standard LFT form, we consider the problem of designing robust L2-gain disturbance feedforward controllers if the uncertain blocks are described by integral quadratic constraints (IQCs). For technical reasons related to the feedforward problem we work with the duals of the constraints involved in robustness analysis using IQCs. Based on an elimination of t...
