Passivity-based finite-time attitude control problem

In this paper the passivity-based finite-time attitude control problem of a rigid spacecraft is addressed. Firstly, for a certain class of nonlinear passive system we derive different control laws according to different choices of storage functions. Based on this result, combining the sliding mode control method, we propose a passivity-based finite-time controller for a rigid spacecraft. Performances of the proposed controllers are illustrated by simulation.
