Robust asymptotic stabilization of a flexible spacecraft by combination of passivity and sliding mode methods
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 9
Abstract
This paper considers the problem of asymptotic stabilizing of a flexible spacecraft in the presence of inertia uncertainties and external disturbances. In this system the inertia uncertainties are in the kind of matched uncertainties. For this purpose a controller is designed based on the combination of passivity concept and sliding mode method. This controller is robust against external disturbances and inertia uncertainties. In this way the sliding surfaces are designed by passivity concept and then the robust controller is designed by sliding mode method to eliminate the effects of matched uncertainties and external disturbances and guarantees the robust asymptotic stability of the closed-loop system. Also, Computer simulations denote the efficiency of the proposed controller in robust asymptotic stabilizing of the flexible spacecraft.

Analysis of waveguides coupling in Photonic Crystal Power-Splitter
In this paper, we suggest a new power-splitter in two-dimensional photonic crystals which can be used for photonic integrated circuits. The proposed power-splitter mechanisms is similar to three-waveguide directional cou...

Dynamics of Entanglement In Two-Mode Gaussian Open Quantum Systems
In the framework of the theory of open systems, we give a description of quantum entanglement for two non-interacting modes embedded in a common thermal environment. We describe the evolution of entanglement in terms of...
