Robust Stabilization of the Angular Velocity for an Underactuated Rigid Spacecraft

We consider the asymptotic stabilization of the angular velocity for a rigid spacecraft with two control torques. While this is a classical problem in the nonlinear control literature, the issue of robust performance in the presence of perturbations has received less attention. In this paper, we int...

Summary:We consider the asymptotic stabilization of the angular velocity for a rigid spacecraft with two control torques. While this is a classical problem in the nonlinear control literature, the issue of robust performance in the presence of perturbations has received less attention. In this paper, we introduce a new feedback control strategy, based on the recently proposed iterative steering approach. The resulting controller is very simple and prescribes the repeated application of a finite-time steering control designed for the nominal system. Robustness with respect to errors on inertia moments and actuator misalignments is proven theoretically and shown by simulation.
