Robust Stabilization of the Angular Velocity for an Underactuated Rigid Spacecraft

IFAC Proceedings Volumes, 1998
Abstract We consider the asymptotic stabilization of the angular velocity for a rigid spacecraft with two control torques. While this is a classical problem in the nonlinear control literature, the issue of robust performance in the presence of perturbations has received less attention.

Stability Robustness of Closed‐Loop Systems in Angular Metrics

Asian Journal of Control, 2016
AbstractH∞‐norm is widely used in the analysis and synthesis of robust control, a field which continues to flourish and develop. However, H∞‐norm can only be used to measure the distance between two stable systems, not unstable systems. Sometimes, it is not appropriate to measure the gap between two systems. In this paper, a new metric, angular metric,

Stability robustness of control system in angular metric

2013 25th Chinese Control and Decision Conference (CCDC), 2013
The robust control theory based on ∞-norm is the successful example of solving the robust control problem, which has become a fairly systematic theory. However, ∞-norm can only be used to measure the distance between two stable systems not the unstable systems. Sometimes, it is not appropriate to measure the gap of two stable systems.

Transient stability angular increment computer

Electrical Engineering, 1956
DETERMINATION of the transient-stability limit of a power system requires expressing the rotor angle of each machine or group of machines in the system as a function of time following the initial disturbance. This problem has been solved using miniature dynamic systems, digital computers, and differential analyzers.

Robust stabilization of the angular velocity of a rigid body

Proceedings of the 36th IEEE Conference on Decision and Control, 1998
The problem of robust control for the angular velocity of a rigid body subject to external disturbances is addressed. It is shown that if the disturbances are matched there exists a Lipschitz continuous control law attenuating the effect of the disturbances; whereas in the case of non-matched disturbances no such a feedback law exists.

The stability of temporary prosthetic base materials I: Introduction, angular changes and dimensional stability

Journal of Oral Rehabilitation, 1993
The bases of occlusal rims and trial dentures should fit both the cast and the mouth accurately. The retention of shape and dimension of strips and sheets of grey and pink shellac, filled cold cure acrylic resin and wax were tested following moulding over stylised upper edentulous casts.

Complex fractures of the distal radius treated with angular stability plates

MUSCULOSKELETAL SURGERY, 2009
Complex fractures of the distal radius are articular lesions and comminuted at the level of the epiphysis and metaphysis. Their treatment is difficult and in most cases surgical. Of all the different osteosynthesis methods available, internal fixation with plate and screws is the most commonly used.
