A Robust Optimization Approach for Magnetic Spacecraft Attitude Stabilization
Attitude stabilization of spacecraft using magnetorqers can be achieved by a proportional-derivative-like control algorithm. The gains of this algorithm are usually determined by using a trial-and-error approach within the large search space of the possible values of the gains. However, when finding the gains in this manner, only a small portion of the search space is actually explored. We prop...
متن کاملRobust Attitude Stabilization of Spacecraft Using Minimal Kinematic Parameters
In this paper, we consider the problem of three-axis robust attitude stabilization of a rigid spacecraft using minimal, three-dimensional kinematic parameters. New nonlinear control laws having a class of relaxed feedback gain structures are proposed, and are shown to provide a robustness with respect to inertia uncertainties of a rigid body. A numerical example is given to illustrate the theor...
متن کاملAttitude stabilization of a rigid spacecraft using two control torques: A nonlinear control approach based on the spacecraft attitude dynamics
-The attitude stabilization problem of a rigid spacecraft using control torques supplied by gas jet actuators about only two of its principal axes is considered. If the uncontrolled principal axis of the spacecraft is not an axis of symmetry, then the complete spacecraft dynamics are small time locally controllable. However, the spacecraft cannot be asymptotically stabilized to any equilibrium ...
متن کاملEarth’s Magnetic Field for Spacecraft Attitude Control Applications (TECHNICAL NOTE)
In this paper the earth’s magnetic field is simulated precisely while the intensity and direction of the field are verified with one of the standard references for selected points on the earth and the results are compared with some low-order models. In another simulation, the complete model is compared with a common approximate model. The magnetic field in orbital frame is described and to empl...
متن کاملNonlinear Robust Control for Spacecraft Attitude
This paper proposed a nonlinear robust control for spacecraft attitude based on passivity and disturbance suppression vector. The spacecraft model was described using quaternion. The control law introduced the suppression vector of external disturbances and had no information related to the system parameters. The desired performance of spacecraft attitude control could be achieved using the des...
