Adaptive Asymptotic Tracking of Spacecraft Attitude Motion with Inertia Matrix Identification
TL;DR: The problem of a spacecraft tracking a desired trajectory is addressed and addressed using adaptive feedback control using a sixth-order dynamic compensator and a Lyapunov argument is used to show that tracking is achieved globally.

TL;DR: In this paper, the authors derived nonlinear feedback control laws that not only despin the rotor but also bring its translational motion to rest using partial feedback linearization and integrator backstepping schemes.
A benchmark problem for nonlinear control design: problem statement, experimental testbed, and passive nonlinear compensation

TL;DR: In this paper, a translational oscillator with an attached eccentric rotational proof mass actuator is considered, where the nonlinear coupling between the rotational motion of the actuator and the translational motions of the oscillator provides the mechanism for control.

A Subharmonic Vibration Absorber for Rotating Machinery
TL;DR: In this article, the authors demonstrate a dynamic vibration absorber system which can be used to reduce speed fluctuations in rotating machinery, where the absorbers are tuned to one-half of the frequency of the applied torque and more importantly, they are effective in the fully nonlinear operating range.

TL;DR: In this paper, the problem of a spacecraft tracking a desired trajectory is defined and addressed using adaptive feedback control, which has the form of a sixth-order dynamic compensator, does not require knowledge of the inertia of the spacecraft.
