A Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
متن کاملLarge Scale Structure survey
Galaxy groups and low-mass clusters provide important laboratories in which to study X-ray gas physics and the interplay between galaxy evolution and environmental effects. The X-ray Multi-Mirror (XMM) Large Scale Structure (LSS) survey has currently imaged 5 deg 2 to a nominal extended source flux limit of order 10 −14 ergs s −1 cm −2 and is dominated numerically by low-mass groups and cluster...
متن کاملLarge scale structure
I give a review of catalogues of galaxies, clusters of galaxies and superclusters – sources of information to study the large-scale structure of the Universe. Thereafter I shall discuss the power spectrum of density perturbations, and the correlation function – principal description functions which characterize the large-scale structure. I shall pay special attention to the geometric interpreta...
متن کاملSimulating Large - Scale Structure
After two decades of direct dynamical simulation of large–scale structure in the universe, it is safe to say the subject is now " mature ". Still, there are parts of the problem that are less well developed than others. In general, the collisionless dynamics of the dark matter component is better understood than the collisional gas dynamics of the baryonic component. In situations where the gas...
متن کاملModels of Large-scale E-learning
Early interest in e-learning focused around the possibility of large-scale courses. This led to pronouncements of the demise of the educator, which were based on an infinite lecture hall pedagogy. However, cost-effective models of large-scale e-learning have proven difficult to implement. This paper examines some of the initial reaction to the notion of large-scale courses and sets out the cost...
