In this paper, the attitude control for rapid maneuvers with Rodrigues parameters representation is addressed. We consider the bounded finite-time stability problem by using a combing control strategy. Considering the efficiency of control and disturbance effect, a constrained domain is designed, based on which a combined control law is proposed for the rapid maneuvering task. Finally, a simulation...
This paper investigates the attitude control problem of on-orbit servicing spacecraft which changes moment of inertia after the rendezvous and docking task. Considering in the small-angle circumstance and manipulating attitude dynamics model with linearization method, the attitude controller based on pole assignment is obtained. Finally, a numerical example is provided to illustrate the effectiveness...
A serial of Translational Meshing Motors (TMM) have being developed recently, but it is a multivariable, strong coupling and highly nonlinear system which has lots of difficulties to model and Analysis. A simpler and quite accurate model based on finite element method is presented to analyze the nonlinear characteristics and dynamic characteristic of motor in this paper. The geometry structure, electromagnetic...
The paper presents a quaternion-based attitude control algorithm which is subject to control input constraints for rigid spacecrafts. Lyapunov theory is employed to prove the global asymptotic stability of the zero equilibrium points of the close loop system. Also the algorithm is validated by the corresponding hardware-in-the-loop (HIL) simulation using a single-axis air bearing table and other hardware...
