Fuzzy Sliding Mode for Spacecraft Formation Control in Eccentric Orbits

A. Imani; M. Bahrami

Volume 7, Issue 1 , April 2014, , Pages 49-56

Abstract
  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 ...  Read More

Robust Control of Spacecraft Formation Flying Using Optimal Sliding Mode

A. Imani; M. Bahrami

Volume 6, Issue 1 , April 2013, , Pages 69-75

Abstract
  In this paper, in order to control the relative motion for spacecraft formation flying, an optimal sliding mode controller is presented. This controller is designed based on the linearized equations of relative motion in circular orbit and applied to nonlinear system that is subjected to external disturbance. ...  Read More

Dynamics Modeling of Spacecraft Formation Flying and Evaluating the Models Accuracy under the Effects of Relative Distance, Eccentricity and Earth Gravitational Perturbation

M. Navabi; M. Barati

Volume 5, Issue 1 , April 2012, , Pages 51-59

Abstract
  Relative motion of satellites in a formation can be studied in several forms of dynamics models. In this paper, some of the most applicable models each implying particular assumptions, constraints and specifications are described in Cartesian and orbital element spaces. Despite the significant applications ...  Read More
