H2/H∞ Controller Design for Singular Perturbation Systems

چکیده
In this paper the synthesis of logic-based switching H2/H∞ state-feedback controller for singular perturbation systems is considered that achieves a minimum bound on the H2 performance level, while satisfying the prescribed H∞ performance. The proposed hybrid control scheme is based on a fuzzy supervisor which manages the combination of two controllers. A convex LMIbased formulation of the two fast and slow subsystem controllers leads to a structure that ensures a good performance in both the transient and the steady state phase. It is shown that the system with the proposed controller remains globally stable despite the configuration (controller) changing. [Fatemeh Jamshidi, Afshin Shaabany.

Singular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...

A singularly perturbed model is proposed for a system comprised of a PEM Fuel Cell(PEM-FC) with Natural Gas Hydrogen Reformer (NG-HR). This eighteenth order system is decomposedinto slow and fast lower order subsystems using singular perturbation techniques that provides tools forseparation and order reduction. Then, three different types of controllers, namely an optimal full-order,a near-opti...

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...
