Computing polytopic controlled invariant sets which are maximal inside a prescribed region often yields sets which have a really complex representation. Since the associated control has a complexity which drastically increases with that of the region, this turns out to be a major problem in the implementation of the theory of controlled invariant regions. In this paper, we consider the problem ...

The H2 performance specification for onedimensional systems has been known to be analytically and practically meaningful and widely used in the analysis and design of control and filtering systems. However, it is still of little use in the analysis and design of two-dimensional systems due to the structural and dynamical complexity of two-dimensional systems. In this paper, we extend the classi...

In this paper, the problem of linear parameter varying (LPV) filter design for timevarying discrete-time polytopic systems with bounded rates of variation is investigated. The design conditions are obtained by means of a parameter-dependent Lyapunov function and extra variables for the filter design, expressed as bilinear matrix inequalities. An LPV filter, which minimizes an upper bound to the...

In this study an observer-based novel design of robust control system with an estimate scheme of sensor states to accommodate extended bounded-sensor faults is proposed. The sensor faults are, in general, modeled as polytopic bounds in robust control framework and are usually given as a priori assumption. But, in practice, the sensors that are subject to faults are especially vulnerable to vari...

Power electronics based zonal dc power distribution systems are being considered for future Navy ships. The stability of dc power electronics based power distribution systems, and in particular dc systems, is a significant design consideration because of the potential for negative impedance induced instabilities. In this paper, methodologies for analyzing the stability of these systems are revi...

This paper develops a hybrid/gain scheduled controller for moving the state of a diesel engine through a driving profile represented as a sequence of operating points in the seven-dimensional state space of a mean value breathing nonlinear engine state model. The calculations for the control design are based on a third-order (reduced) model of the diesel engine, on whose state space the operati...

We present a numerical approximation of Darcy's flow through porous medium that incorporates networks fractures with non empty intersection. Our scheme employs PolyDG methods, i.e. discontinuous Galerkin methods on general polygonal and polyhedral (polytopic, for short) grids, featuring elements edges/faces may be in arbitrary number (potentially unlimited) whose measure arbitrarily small. appr...

[VNb12O40]15− polytopic ligand can coordinate to up five {(C6H6)Ru}2+ groups. Combined analytical separation tools together with 1H DOSY NMR were firstly applied the solution studies of polyoxoniobate based complexes.
