For most satellite missions, it is essential to decrease the satellite angular velocity. TheΒ algorithm is a common algorithm to stabilize the spacecraft by using magnetorquers. Controlling the satellite using the magnetorquers is part of the attitude control subsystem detumbling mode. Due to oscillating disturbances in the space environment, the required initial conditions needs analysis. As a...

The impact of two predictor variables (estimated knee extensor fast-twitch fiber percentage, body mass) on performance measures (vertical jump power output, leg press peak angular velocity) were examined. Subjects (25 men, 27 women) performed 5 workouts involving 2 vertical jump, leg press, and 50-repetition isokinetic tests (to estimate knee extensor fast-twitch fiber percentage). Multivariate...

Hamilton-Jacobi-Bellman theory is shown to provide a unified framework for nonlinear feedback control laws for special classes of nonlinear systems. These classes include Jurdjevic-Quinn type systems, as well as minimum phase systems with relative degree {1, 1 . . . . . 1}. Several examples are given to illustrate these results. For the controlled Lorenz equation, results obtained by Vincent an...

[1] Plate kinematics have been derived from GPS site velocities spanning Australasia and the western Pacific and define a framework in which deformation fields at plate boundaries can be investigated. The Australian Plate appears to be rigid from Cocos Island in the west to Noumea in the east and incorporating all of the Australian continent. A revision of the angular velocity vector of the Pac...

This paper proposes a robust path-following control method of a kinematic mobile robot system subject to bounded angular velocity error. The angular velocity error usually arises from imperfect performance of the dynamic control system. Given a kinematic model of the mobile robot system with bounded angular velocity error, we present a stable and robust path-following controller which is based ...

It is well documented that the ability of human muscles to develop tension is dependent on the angular velocity. In concentric actions, the decline of maximal voluntary torque, consequential to a velocity increase, has been extensively studied. The underlying mechanisms may be attributed to either or both chemical and mechanical muscle properties and/or motor unit activation by the central nerv...
