Abstract

This paper presents a new control method for satellite attitude control systems with input constraints. By augmenting a bounded hyperbolic tangent function into the control variables, the attitude control system is transformed to a higher-order configuration, thereby solving the input constraint issue. The obtained controller enables finite-time stability for the attitude control system. It demonstrates that the convergence time of the state trajectory is inversely proportional with the input constraints. The efficacy of the proposed approach is validated through simulation examples.
