Verification of a Low Cost Method for Accelerometers Calibration with a Two-Axis Table

Mohsen Bahrami; Behzad Parsi

Volume 7, Issue 4 , January 2015, , Pages 73-79

Abstract
  In this paper a low cost calibration method which can calibrate with measuring the sensor displacement is suggested. To verify this calibration method a two-axis table, which is expensive, with artificial neural network (ANN) for mapping non-linear relationships between the inputs and outputs is used. ...  Read More

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
