Attitude control of a spacecraft using self-triggered control approach

Modern spacecraft systems refer to an engineering platform that depend on the integration of physical systems with control, computation, and communication technologies. In this paper, a self-triggered control approach is introduced for the spacecraft attitude control problem. The self-triggered control proposed in this paper guarantees the desirable stabilization behavior of the spacecraft. Besides, it allows a reduction of the computation and communications demand. Furthermore, we derive the equations of attitude motion. A general procedure leading to self-triggered implementations of feedback controllers on a rigid spacecraft has been developed as well. Finally, the efficiency and feasibility of the obtained results is illustrated by means of a numerical example.
