In this note, we consider the finite-time stabilization of discrete-time linear systems subject to disturbances generated by an exosystem. Finite-time stability can be used in all those applications where large values state should not attained, for instance presence saturations. The main result provided note is a sufficient condition via feedback. This then find some conditions existence output feedback controller guaranteeing stability. All are reduced feasibility problems involving matrix...
The note deals with the finite-time analysis and design problems for continuous-time, time-varying linear systems. Necessary sufficient conditions a condition stability are devised. Moreover, solvability of both state output feedback stated. Such results require feasibility optimization involving Differential Linear Matrix Inequalities. Some numerical examples illustrate effectiveness proposed approach.
Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...

In this brief, we consider the problem of 3-D path generation and tracking for unmanned air vehicles (UAVs). The proposed algorithm allows us to find a satisfying arbitrary initial final conditions, specified in terms position velocity. Our method assumes that aircraft structural dynamic limitations can be translated turn radius constraint; therefore, generated paths satisfy constraint on minimum admissible turning radius. guarantees, under assumptions, error, both attitude, asymptotically...

An initial concept for the plasma diagnostic and control (D&C) system has been developed as part of European studies towards development a demonstration tokamak fusion reactor (DEMO). The main objective is to develop feasible, integrated design DEMO D&C that can provide reliable high performance (electricity output) over extended periods operation. While power maximized when operating near operational limits tokamak, reliability operation typically improves choosing parameters significantly...

The aims to use combination heating current drive (H&CD) systems—and optionally poloidal field (PF) system—in an optimal way regulate evolution parameter profiles such as...
Abstract Robust finite‐time stability (FTS) for a class of uncertain hybrid systems is tackled the first time in this paper. In particular, impulsive dynamical linear (U‐IDLS) are considered. U‐IDLS exhibit jumps state trajectory that can be either time‐driven (time‐dependent IDLS) or driven by specific values (state‐dependent IDLS). Furthermore, may uncertainties both dynamic and jump equation. paper, sufficient conditions FTS IDLS provided. These results require solution feasibility...
