Fuzzy Sliding Mode for Spacecraft Formation Control in Eccentric Orbits
The problem of relative motion control for spacecraft formation flying in eccentric orbits is considered in this paper. Due to the presence of nonlinear dynamics and external disturbances, a robust fuzzy sliding mode controller is developed. The slopes of sliding surfaces of the conventional sliding mode controller are tuned according to error states using a fuzzy logic and reach the pre-define...
متن کاملQuantization of Nilpotent Coadjoint Orbits Quantization of Nilpotent Coadjoint Orbits Quantization of Nilpotent Coadjoint Orbits
Let G be a complex reductive group. We study the problem of associating Dixmier algebras to nilpotent (co)adjoint orbits of G, or, more generally, to orbit data for G. If g = 0 + n + in is a triangular decomposition of g and 0 is a nilpotent orbit, we consider the irreducible components of 0 n n, which are Lagrangian subvarieties of 0. The main idea is to construct, starting with certain "good"...
متن کاملOrbits, Weak Orbits and Local Capacity of Operators
Let T be an operator on a Banach space X. We give a survey of results concerning orbits {Tnx : n = 0, 1, . . .} and weak orbits {〈Tnx, x∗〉 : n = 0, 1, . . .} of T where x ∈ X and x∗ ∈ X∗. Further we study the local capacity of operators and prove that there is a residual set of points x ∈ X with the property that the local capacity cap(T, x) is equal to the global capacity cap T . This is an an...
متن کاملRandom Homoclinic Orbits
We introduce random homoclinic points and orbits for random dynamical systems with hyperbolic stationary orbits and investigate their meaning for irregular behaviour in form of a stochastic version of the Birkhoo-Smale Theorem. In particular we show that transversal random homoclinic points cause a conjugacy of the random dynamical system in a part of the phase space to a random shift system.
متن کاملHomotopy of State Orbits
Let M be a von Neumann algebra, φ a faithful normal state and denote by M the fixed point algebra of the modular group of φ. Let UM and UMφ be the unitary groups of M and M. In this paper we study the quotient Uφ = UM/UMφ endowed with two natural topologies: the one induced by the usual norm of M (called here usual topology of Uφ), and the one induced by the pre-Hilbert C∗-module norm given by ...
