This paper is concerned with the development of a control system for rotational maneuver and vibration suppression of a flexible spacecraft. It is assumed that the system parameters are unknown. The design approach presented here treats the problem of spacecraft attitude control separately from the elastic vibration suppression problem. As a stepping stone, a state feedback sliding mode control...

This paper investigates active real-time balancing of rigid rotors during the transient time of acceleration. First, the governing equation of motion of a rigid rotor is formulated. A parametric adaptive control scheme is then designed based on this dynamic model. An ordinary recursive least squares estimation method is used to estimate parameters in this adaptive control scheme. A supervisory ...

A Hamiltonian is proposed to describe the coupling between vibration and rotation in a molecular system. The time behaviour of such a system exhibits both regular and irregular motion for different energies and different values of the coupling parameter. There is a dramatic manifestation of the transition between the two types of dynamics that define parametric regions of regular and irregular ...
